When doing request level BB logging the hybrid_bw_log() does not have proper screening to minimize logging
when point level logging is in use. Lets fix it properly so you have to have the proper knobs set to get the

When sorting, both the C11 standard (ISO/IEC 9899:2011, K.3.6.3.2) and
the ISO/IEC JTC1 SC22 WG14 N1172 standard, does not define objects of
zero size as undefined behaviour. However Microsoft's cpp-docs does.
Add proper checks for this. Found while working on bsort(3).

The bsort(3) algorithm works by swapping objects, similarly to qsort(3),
and does not require any significant amount of additional memory.
The bsort(3) algorithm doesn't suffer from the processing time issues
known the plague the qsort(3) family of algorithms, and is bounded by
a complexity of O(log2(N) * log2(N) * N), where N is the number of
elements in the sorting array. The additional complexity compared to
mergesort(3) is a fair tradeoff in situations where no memory may
be allocated.
The bsort(3) APIs are identical to those of qsort(3), allowing for
easy drop-in and testing.
The design of the bsort(3) algorithm allows for future parallell CPU
execution when sorting arrays. The current version of the bsort(3)
algorithm is single threaded. This is possible because fixed areas
of the sorting data is compared at a time, and can easily be divided
among different CPU's to sort large arrays faster.

Both pf_rules_lock and pf_ioctl_lock only ever affect one vnet, so
there's no point in having these locks affect other vnets.
(In fact, the only lock in pf that can affect multiple vnets is
pf_end_lock.)
That's especially important for the rules lock, because taking the write
lock suspends all network traffic until it's released. This will reduce
the impact a vnet running pf can have on other vnets, and improve
concurrency on machines running multiple pf-enabled vnets.

The explanation from https://reviews.freebsd.org/D39637 by stevek:
The "use_xsave" variable is a global and that is only supposed to be
initialized early before scheduling gets started. However, with the way
the ifuncs for "fpusave" and "fpurestore" are implemented, the value
could be changed at runtime when scheduling is active if "use_xsave"
was set to 0 by the tunable. This leaves a window of opportunity where
"use_xsave" gets re-initialized to 1 and a context switch could occur
with a thread that was not set up to be able to use xsave functionality.
This can lead to an "privileged instruction fault".
The fix is to protect "use_xsave" from being initialized more than once.

Pass 1 of fsck_ffs checks the integrity of all the cylinder groups.
If any are found to have been corrupted it offers to rebuild them.
Pass 5 then makes a second pass over the cylinder groups to validate
their block and inode maps. Pass 5 assumes that the cylinder groups
are not corrupted and can segment fault if they are corrupted. Rather
than rerunning the corruption checks a second time in pass 5, this
fix keeps track whether any corrupt cylinder groups were found but not
fixed in pass 1 either due to running with the -n flag or by explicitly
answering `no' when asked whether to fix a corrupted cylinder group.
If any corrupted cylinder groups remain after pass 1, fsck_ffs will
decline to run pass 5. Instead it marks the filesystem as unclean
so that fsck_ffs will need to be run again before the filesystem can
be mounted.
This patch cleans up and documents the return value from check_cgmagic().
It also renames the variable / parameter "rebuildcg" to "rebuiltcg".
This parameter describes whether the cylinder group has been rebuilt
rather than whether it should be rebuilt.
