Add -c to zpool iostat & status to run command
This patch adds a command (-c) option to zpool status and zpool iostat. The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat. The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command. For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful
if the command you're running requires a /dev/sd* device.
The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper. This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root. This means that UDEV_UPATH get set correctly
when running zpool status/iostat as an unprivileged user.
Example:
$ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH'

Batch free zpl_posix_acl_release
Currently every calls to zpl_posix_acl_release will schedule a delayed task,
and each delayed task will add a timer. This used to be fine except for
possibly bad performance impact.
However, in Linux 4.8, a new timer wheel implementation[1] is introduced. In
this new implementation, the larger the delay, the less accuracy the timer is.
So when we have a flood of timer from zpl_posix_acl_release, they will expire
at the same time. Couple with the fact that task_expire will do linear search
with lock held. This causes an extreme amount of contention inside interrupt
and would actually lockup the system.
We fix this by doing batch free to prevent a flood of delayed task. Every call
to zpl_posix_acl_release will put the posix_acl to be freed on a lockless
list. Every batch window, 1 sec, the zpl_posix_acl_free will fire up and free
every posix_acl that passed the grace period on the list. This way, we only
have one delayed task every second.
This patch addresses multiple 'zpool import' block device
indentification problems which are most likely to occur on a
system configured to use blkid, by_vdev paths, multipath and
failover. The symptom most commonly observed is the import
uses different path names to import the pool than would
normally be expected.
* When using blkid to identify vdevs the listed devices may
be added to the cache in any order. In order to apply the
preferred search order heuristic a zfs_path_order() function
was added to calculate the order given full path names.
* Since it's possible to have multiple block devices with
different vdev guids which refer to the same ZPOOL_CONFIG_PATH
the slice cache must be indexed by guid and name. By avoiding
collisions the preferred ordering can be maintaining even
when multiple block devices claim the same ZPOOL_CONFIG_PATH.
The preferred sorting by partition was never benefitial for
a Linux system and was removed as part of this change.
* When adding entries to the blkid cache avl_find/avl_insert
are used instead of avl_add because collisions are possible
and must be handled gracefully.
* For pools using multipath devices there are, at a minimum,
three devices where a vdev label may be read. They are the
dm-* device and each underlying /dev/sd* device. Due to the
way the block cache is implemented each of these devices may
have a different cached copy of the vdev label. This can
result in "ghost pools" which appear to persist even after
a 'zpool labelclear' has been done to the dm-* device. In
order to prevent this the vdev label is read with O_DIRECT
in order to bypass any caching to get the on-disk version.
* When opening a block device verify that vdev guid read from
the disk matches the expected vdev guid. This allows for bad
labels to be filtered out.

In the previous code, statechange-led was only looking at the UNAVAIL->ONLINE
transition to turn off the LED. It ignored the #2 ONLINE->UNAVAIL transition,
assuming it was just the "old" VDEV going offline. This is problematic, as
a drive can go from ONLINE->UNAVAIL when it's malfunctioning, and we don't want

Multipath autoreplace, control enclosure LEDs, event rate limiting
1. Enable multipath autoreplace support for FMA.
This extends FMA autoreplace to work with multipath disks. This
requires libdevmapper to be installed at build time.
2. Turn on/off fault LEDs when VDEVs become degraded/faulted/online
Set ZED_USE_ENCLOSURE_LEDS=1 in zed.rc to have ZED turn on/off the enclosure
LED for a drive when a drive becomes FAULTED/DEGRADED. Your enclosure must
be supported by the Linux SES driver for this to work. The enclosure LED
scripts work for multipath devices as well. The scripts will clear the LED
when the fault is cleared.
3. Rate limit ZIO delay and checksum events so as not to flood ZED
ZIO delay and checksum events are rate limited to 5/sec in the zfs module.

Properly use the Dracut cleanup hook to order pool shutdown
When Dracut starts up, it needs to determine whether a pool will remain
"hanging open" before the system shuts off. In such a case, then the
code to clean up the pool (using the previous export -F work) must
be invoked. Since Dracut has had a recent change that makes
mount-zfs.sh simply not run when the root dataset is already mounted,
we must use the cleanup hook to order Dracut to do shutdown cleanup.

When write I/Os are issued, they are issued in block order but the ZIO
pipeline will drive them asynchronously through the allocation stage
which can result in blocks being allocated out-of-order. It would be
nice to preserve as much of the logical order as possible.
In addition, the allocations are equally scattered across all top-level
VDEVs but not all top-level VDEVs are created equally. The pipeline
should be able to detect devices that are more capable of handling
allocations and should allocate more blocks to those devices. This
allows for dynamic allocation distribution when devices are imbalanced
as fuller devices will tend to be slower than empty devices.
The change includes a new pool-wide allocation queue which would
throttle and order allocations in the ZIO pipeline. The queue would be
ordered by issued time and offset and would provide an initial amount of
allocation of work to each top-level vdev. The allocation logic utilizes
a reservation system to reserve allocations that will be performed by
the allocator. Once an allocation is successfully completed it's
scheduled on a given top-level vdev. Each top-level vdev maintains a
maximum number of allocations that it can handle (mg_alloc_queue_depth).
The pool-wide reserved allocations (top-levels * mg_alloc_queue_depth)
are distributed across the top-level vdevs metaslab groups and round
robin across all eligible metaslab groups to distribute the work. As
top-levels complete their work, they receive additional work from the
pool-wide allocation queue until the allocation queue is emptied.
