MFC r295385: semget(): Check for [EEXIST] error first.
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.

MFC r266615: Increase taskqueue thread priority from idle to PRIBIO.
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.

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

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.

Make dynamic link of libiconv from ports work again.

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.
MFC r297232: Unify ignoring EEXIST from zvol_create_minor().
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.
m_unshare passes on the source mbuf's flags as-is to m_getcl and this
results in a leak if the flags include M_NOFREE. The fix is to clear
the bits not listed in M_COPYALL before calling m_getcl. M_RDONLY
should probably be filtered out too but that's outside the scope of this
fix.
Add assertions in the zone_mbuf and zone_pack ctors to catch similar
bugs.
Update netmap_get_mbuf to not pass M_NOFREE to m_getcl. It's not clear
what the original code was trying to do but it's likely incorrect.
Updated code is no different functionally but it avoids the newly added
assertions.
