A future change in lualoader may take some liberties with the
loader_conf_files in the name of efficiency; namely, it may start omitting
it from the loader environment entirely so that it doesn't need to worry
about maintaining any specific value.
This variable has historically been incredibly volatile anyways, as it may
get set to completely different values in any given configuration file to
trigger a load of more files.
Document now that we may not maintain it in the future, but perhaps we'll
reserve the right to change our minds and eventually formally export all of
the loader configuration files that were read using this variable.

With these two ioctls implemented in the nda driver, nvmecontrol now
works with nda just like it does with nvd. It eliminates the need to
jump through odd hoops to get this data.
Add the nvmeX device to the XPT_PATH_INQ nvme specific
information. while one could figure this out by looking up the
domain🚌slot:function, it's a lot easier to have the SIM set it
directly since the sim knows this.
which can cause a TCP client to use invalid or stale TCP sequence numbers for ACK packets.
Packets with old sequence numbers are ignored and not used to update the send window size.
This might cause the TCP session to hang indefinitely under some circumstances.

This behavior is most relevant for ipfw(4) as documented in syslog.conf(5).
The recent addition of property-based regex filters in r359327 is a
fine workaround for this but the behavior was present since 1997 and
documented.
This only fixes local matching of the "kernel program". It does not
change the forwarded format at all. On the remote side it will still
be "kernel: ipfw:" and not be parsed as a kernel message. This matches
old behavior.

This may happen, for instance, if one happens to have an alias of diff to
diff -up and attempts to specify the amount of context on top of that.
Aliases like this may cause other problems, but if they're really not ever
generating non-unified diffs then we should at least not break that
use-case.
In addition, we'll now pick up a format mismatch if -p is specified with
!contextual && !unified && !unset.
Fix up a small trailing whitespace nit in the tests while we're here, and
add tests to make sure that we can double up all the formatting options.

vm_page_release_locked() releases the last wiring, in which case
vm_page_release_locked() must not free the page. Once the xbusy lock is
acquired, that, the object lock and the fact that the page is unmapped
