-The Solaris Porting Layer (SPL) is a Linux kernel module which provides
-many of the Solaris kernel APIs. This shim layer makes it possible to
-run Solaris kernel code in the Linux kernel with relatively minimal
-modification. This can be particularly useful when you want to track
-upstream Solaris development closely and do not want the overhead of
-maintaining a large patch which converts Solaris primitives to Linux
-primitives.
-
-To build packages for your distribution:
-
- $ sh autogen.sh
- $ ./configure
- $ make pkg
-
-If you are building directly from the git tree and not an officially
-released tarball you will need to generate the configure script.
-This can be done by executing the autogen.sh script after installing
-the GNU autotools for your distribution.
-
-To copy the kernel code inside your kernel source tree for builtin
-compilation:
-
- $ sh autogen.sh
- $ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
- $ ./copy-builtin /usr/src/linux-...
-
-The SPL comes with an automated test suite called SPLAT. The test suite
-is implemented in two parts. There is a kernel module which contains
-the tests and a user space utility which controls which tests are run.
-To run the full test suite:
-
- $ sudo insmod ./module/splat/splat.ko
- $ sudo ./cmd/splat --all
-
-Full documentation for building, configuring, testing, and using the
-SPL can be found at: <http://zfsonlinux.org>

-dnl # DESCRIPTION:
-dnl # Read meta data from the META file. When building from a git repository
-dnl # the SPL_META_RELEASE field will be overwritten if there is an annotated
-dnl # tag matching the form SPL_META_NAME-SPL_META_VERSION-*. This allows
-dnl # for working builds to be uniquely identified using the git commit hash.
-dnl #
-dnl # The META file format is as follows:
-dnl # ^[ ]*KEY:[ \t]+VALUE$
-dnl #
-dnl # In other words:
-dnl # - KEY is separated from VALUE by a colon and one or more spaces/tabs.
-dnl # - KEY and VALUE are case sensitive.
-dnl # - Leading spaces are ignored.
-dnl # - First match wins for duplicate keys.
-dnl #
-dnl # A line can be commented out by preceding it with a '#' (or technically
-dnl # any non-space character since that will prevent the regex from
-dnl # matching).
-dnl #
-dnl # WARNING:
-dnl # Placing a colon followed by a space or tab (ie, ":[ \t]+") within the
-dnl # VALUE will prematurely terminate the string since that sequence is
-dnl # used as the awk field separator.
-dnl #
-dnl # KEYS:
-dnl # The following META keys are recognized:
-dnl # Name, Version, Release, Date, Author, LT_Current, LT_Revision, LT_Age
-dnl #

- * Two approaches to atomic operations are implemented each with its
- * own benefits are drawbacks imposed by the Solaris API. Neither
- * approach handles the issue of word breaking when using a 64-bit
- * atomic variable on a 32-bit arch. The Solaris API would need to
- * add an atomic read call to correctly support this.
- *
- * When ATOMIC_SPINLOCK is defined all atomic operations will be
- * serialized through global spin locks. This is bad for performance
- * but it does allow a simple generic implementation.
- *
- * When ATOMIC_SPINLOCK is not defined the Linux atomic operations
- * are used. This is safe as long as the core Linux implementation
- * doesn't change because we are relying on the fact that an atomic
- * type is really just a uint32 or uint64. If this changes at some
- * point in the future we need to fall-back to the spin approach.

-.TH splat 1 "2013 MAR 16" "ZFS on Linux" "User Commands"
-
-.SH NAME
-splat \- Solaris Porting LAyer Tests
-.SH SYNOPSIS
-.LP
-.BI "splat [\-chvx] < \-\-all | \-\-list | \-\-test " "subsystem" ":" "test" " [...] >"
-
-.SH DESCRIPTION
-This utility uses the splat.ko kernel module to test the spl.ko kernel
-module. Run "modprobe splat" before invoking \fBsplat\fR.
-
-.SH OPTIONS
-.HP
-.BI "\-a" "" ", \-\-all" ""
-.IP
-Run all available tests on all subsystems.
-.HP
-.BI "\-c" "" ", \-\-nocolor" ""
-.IP
-Disable output highlighting. By default, "Fail" is printed in red text
-and "Pass" is printed in green text.
-.HP
-.BI "\-h" "" ", \-\-help" ""
-.IP
-Print the usage message.
-.HP
-.BI "\-l" "" ", \-\-list" ""
-.IP
-For each spl.ko subsystem, print all available test names and
-hexadecimal identifiers with a short description.
-.HP
-.BI "\-t" " subsystem" ":" "test" ", \-\-test" " subsystem" ":" "test"
-.HP
-.BI "\-t" " subsystem" ":all" "" ", \-\-test" " subsystem" ":all" ""
-.IP
-Run the \fItest\fR diagnostic routine for the spl.ko \fIsubsystem\fR.
-Specify this option more than once to run multiple tests.
-
-The \fItest\fR and \fIsubsystem\fR parameters are the names or
-hexadecimal identifiers returned by the \fBsplat --list\fR command.
-
-If \fIsubsystem\fR is a name and not a hexadecimal identifier, then the
-\fBall\fR keyword can be used to run all available \fIsubsystem\fR
-tests.
-
-.HP
-.BI "\-v" "" ", \-\-verbose" ""
-.HP
-.IP
-Increase verbosity.
-.HP
-.BI "\-x" "" ", \-\-exit" ""
-.IP
-Stop running tests after the first failure.
-
-.SH "EXAMPLES"
-.LP
-Test everything in the spl.ko kernel module:
-.IP
-# splat --all --verbose
-.LP
-Test the entire kernel memory subsystem:
-.IP
-# splat --test kmem:all
-.LP
-Test the kernel compression and queue waiting facilities:
-.IP
-# splat --test zlib:compress/uncompress --test taskq:wait
-.LP
-This is the same as the previous command, except that the subsystems
-and tests are referenced by hexadecimal identifier instead of by name:
-.IP
-# splat -t 0x0f00:0x0f01 -t 0x0200:0x0204
-
-.SH "NOTES"
-All tests always return a green "Pass" result on a healthy system. Any
-red "Fail" result should be investigated or reported.
-
-.SH "BUGS"
-Some tests can deadlock the kernel if an X11 desktop is running,
-especially if a proprietary blob driver is loaded for the video
-hardware.
-
-.SH "AUTHORS"
-This man page was written by Darik Horn <dajhorn@vanadac.com>.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

- * Solaris Porting LAyer Tests (SPLAT) Test Control Interface.
- *
- * The 'splat' (Solaris Porting LAyer Tests) module is designed as a
- * framework which runs various in kernel regression tests to validate
- * the SPL primitives honor the Solaris ABI.
- *
- * The splat module is constructed of various splat_* source files each
- * of which contain regression tests for a particular subsystem. For
- * example, the splat_kmem.c file contains all the tests for validating
- * the kmem interfaces have been implemented correctly. When the splat
- * module is loaded splat_*_init() will be called for each subsystems
- * tests. It is the responsibility of splat_*_init() to register all
- * the tests for this subsystem using the splat_test_init().
- * Similarly splat_*_fini() is called when the splat module is removed
- * and is responsible for unregistering its tests via the splat_test_fini.
- * Once a test is registered it can then be run with an ioctl()
- * call which specifies the subsystem and test to be run. The provided
- * splat command line tool can be used to display all available
- * subsystems and tests. It can also be used to run the full suite
- * of regression tests or particular tests.
