Since we do not own the session lock, a parallel killjobc() might
reset s_leader to NULL after we checked it. Read s_leader only once
and ensure that compiler is not allowed to reload.
While there, make access to t_session somewhat more pretty by using
local variable.

luacheck rightfully complains that i is unused in the show-module-options
loop at the end (it was used for some debugging in the process).
We've added a new pager module that's compiled in, so declare that as an
acceptable global.
This effectively dumps everything lualoader knows about to the console using
the libsa pager; that particular lua interface was added in r368591.
A pager stub implementation has been added that just dumps the output as-is
as a compat shim for older loader binaries that do not have lpager. This
stub should be moved into a more appropriate .lua file if we add anything
else that needs the pager.
This is just a minor optimization, but it's sensitive. This gives an improvement of 30-50 kpps.

The existing logic is nice in theory, but in practice freebsd-update will
not preserve the timestamps on these files. When doing a major upgrade, e.g.
from 12.1-RELEASE -> 12.2-RELEASE, pwd.mkdb et al. appear in the INDEX and
we clobber the timestamp several times in the process of packaging up the
existing system into /var/db/freebsd-update/files and extracting for
comparisons. This leads to these files not getting regenerated when they're
most likely to be needed.
Measures could be taken to preserve timestamps, but it's unclear whether
the complexity and overhead of doing so is really outweighed by the marginal
benefit.
I observed this issue when pkg subsequently failed to install a package that
wanted to add a user, claiming that the user was removed in the process.
bapt@ pointed to this pre-existing bug with freebsd-update as the cause.

Although it is not often needed, the nfscbd(8) should be running when
NFSv4 mounts are done if callback functionality is required.
Callback functionality is required for the NFSv4 server to issue
delegations or pNFS layouts.
This patch adds nfscbd to the mountcritremote's REQUIRED line
to ensure it is started before NFS mounts specified in /etc/fstab
are done.

We're looking for file content differences, so ask the question of git

Current way, hardcoded value plus heuristic is not conform to the PCI(e)

Instead, use the standard PCI(e) capability for determining of

One of the disadvantages of our current busdma code is the fact that
we process the bounced buffer in a page-by-page manner. This means that
the short (subpage) buffer allocated across page boundaries is bounced
to 2 separate pages.
This suboptimal behavior is consistent across all platforms and can be
related to (probably unimplementable or incompatible with bouncing)
BUS_DMA_KEEP_PG_OFFSET flag.
Therefore, allocate one additional page to be fully comply with this
requirement.

The sense_ptr thing is quite broken. As near as I can tell, the

user address the sense buffer should be copied to. It is not

GDB 6.1.1 was released in June 2004 and is long obsolete. It does not
support all of the architectures that FreeBSD does, and imposes
limitations on the FreeBSD kernel build, such as the continued use of
DWARF2 debugging information.
It was kept (in /usr/libexec/) only for use by crashinfo(8), which
extracts some basic information from a kernel core dump after a crash.
Crashinfo already prefers gdb from port/package if installed.
Future work may add kernel debug support to LLDB or find another path
for crashinfo's needs, but in any case we do not want to ship the
excessively outdated GDB in FreeBSD 13.
