In exercise mode we collect data for every available counter on a
program and keep all of that in a directory in /tmp.

sys/_offsetof.h: pacify GCC 12's macro redefinition check
GCC 12 has a strict definition of identity (all characters including
whitespace must be identical) when comparing "redefined" macros. Make
our definition exactly match the stddef.h that comes with GCC to fix
test-includes of netlink/netlink_snl.h. (Note: later versions of GCC
are a bit more flexible and don't have this problem.)

trim(8): minor output correction
"trim /dev/da*" would print the following line multiple times
when given multiple agruments:
dry run: add -f to actually perform the operation
Print it once before looping over arguments.
Also, note possible suffixes P and E after offset/length
as per expand_number(3).

traceroute: MFC: graceful recover after networking errors with as_server
Currently, the traceroute[6] utility does not check
for possible networking errors while talking to as_server
in case of "traceroute -a". Meantime, there is a common case
when trace is long and it has many non-responding hops
(shown as '* * *'), so as_server aborts our connection,
hence no AS numbers shown for the rest of trace.
Somewhat artifical way to reproduce the problem:

kern_syscall_deregister: document syscall 0 no-op logic
Document syscall #0 being handled specially in
`kern_syscall_deregister(..)`: it's a reserved syscall and not

buf: Relax an assertion in BUF_UNLOCK
The BUF_UNLOCK macro asserts that B_REMFREE is not set, as it is up to
the lock owner to complete the dequeue from the free list before
releasing the lock. However, if the thread has acquired the lock
multiple times, then releasing the recursive lock should be ok. Modify
the assertion to reflect this.
This was triggered by an out-of-tree filesystem.

rge: log silicon revision during attach
The initial import from OpenBSD contained chip revision printf() calls
commented out, as OpenBSD's bare printf() style does not translate to
FreeBSD's device_printf() idiom. The result is that users cannot
distinguish RTL8125 from RTL8125B, RTL8125D_1, RTL8125D_2 etc. via
dmesg alone, even though all variants show as '<RTL8125>' from the PCI
probe string.
Add proper device_printf() calls including the raw hwrev value,
consistent with how re(4) reports chip revisions.
