system statistics information (statfs-like, fstatfs-like and ustat).
* Added -e trace=/regex option for filtering syscalls using regular
expressions.
+ * Added support for prepending of question mark before syscall qualification
+ in -e trace expressions in order to suppress error in case no syscalls
+ matched the provided qualification.
* Implemented decoding of signal mask in rt_sigreturn syscall on alpha, arc,
arm, avr32, bfin, cris, hppa, m68k, metag, microblaze, mips, nios2, or1k,
powerpc, powerpc64, riscv, sh, sh64, sparc, sparc64, tile, x86, and xtensa
* Implemented decoding of statx syscall.
* Implemented decoding of NS_* ioctl commands.
* Implemented decoding of the remaining V4L2_BUF_TYPE_* types.
+ * Implemented decoding of VIDIOC_[SG]_TUNER ioctl commands.
* Implemented decoding of NLMSG_ERROR netlink messages.
+ * Improved decoding of BPF_PROG_ATTACH command of bpf syscall.
+ * Improved decoding of misplaced parts in DM_* ioctl commands.
* Updated lists of ioctl commands from Linux 4.11.
* Bug fixes
* Fixed decoding of flags argument of preadv2 and pwritev2 syscalls on x32.
* Fixed the number of arguments and tracing flags of alpha specific syscalls.
* Fixed decoding of netlink messages received within struct msghdr.
+ * Worked around a bug in miscompiled aarch64 kernels leading to the 3rd
+ argument of sched_getattr syscall being not quite 32-bit.
+ * Fixed corner cases of printing inaccessible times argument of utimes
+ and futimesat syscalls.
Noteworthy changes in release 4.16 (2017-02-14)
