* Do not subvert vfs.timestamp_precision by reading the time and passing
that to utimensat(). Instead, pass UTIME_NOW. A fallback to a NULL times
pointer is no longer used.
* Do not ignore -a/-m if the user has write access but does not own the
file. Leave timestamps unchanged using UTIME_OMIT and do not fall back to
a NULL times pointer (which would set both timestamps) if that fails.
Although POSIX literally permits failing with [EINVAL] if IPC_CREAT and
IPC_EXCL were both passed, the semaphore set already exists and has fewer
semaphores than nsems, this does not allow an application to retry safely:
if the [EINVAL] is actually because of the semmsl limit, an infinite loop
would result.

syslogd: Enable repeated line compression for lines of any length.
Enable repeated line compression for lines of any length, instead of only short
lines. AFAICT repeated line compression was limited to short lines as a RAM
optimization, which made sense when karels added it in 1988, but no longer.
The penalty is a paltry 904B of RAM per file logged.
Misc fixes suggested by Coverity.

* In the event that popen fails, don't dereference its return value.
* Fix array overwrite in the stream and seqpacket tests.
* Close sockets at the end of successful ATF tests.
Idle priority is not even time-share, so if system is busy in any way,
those events may never be executed. Since in some cases system waits
for events processed by that thread, that may cause deadlocks.
LinuxKPI atomic fixes:
- Fix implementation of atomic_add_unless(). The atomic_cmpset_int()
function returns a boolean and not the previous value of the atomic
variable.
- The atomic counters should be signed according to Linux.
- Some minor cosmetics and styling while at it.

Use hardware computed Toeplitz hash for incoming flowids
Use the Toeplitz hash value as source for the flowid. This makes the
hash value more suitable for so-called hash bucket algorithms which
are used in the FreeBSD's TCP/IP stack when RSS is enabled.

Fix witness panic in the ipoib_ioctl() function when unloading the
ipoib module.
The bpfdetach() function is trying to turn off promiscious mode on the
network interface it is attached to while holding a mutex. The fix
consists of ignoring any further calls to the ipoib_ioctl() function
when the network interface is going to be detached. The ipoib_ioctl()
function might sleep.

Improve detection of extended QSFP diagnostics.
The standards in the QSFP diagnostics area are not clear when the

Align signal stack pointer to 16 bytes.
The stack must be aligned to 16 bytes at all times. Clang 3.8 is especially

Set watchdog timer parameters only when they really need to be changed.
In other cases just restart the timer with single Reset command instead
of two (Set and Reset).
From one side this visually reduces amount of CPU time burned in tight
loop waiting while some slow BMC configures its watchdog hardware, that
seems to be much more complicated task then just resetting the timer.
From another side on some BMCs those slow Set commands sometimes tend to
timeout, that leads to noisy log messages and even more CPU time burned,
so avoiding them can provide even bigger bonuses.
This fixes creation of zvol devices for snapshots during zfs receive,
that previously failed with "ZFS WARNING: Unable to create ZVOL" message.
This solution is not perfect, but IMHO better then it was before.
