to a new function, fifo_cleanup(), and call fifo_cleanup() from
fifo_close() and the appropriate places in fifo_open().

because RFNOWAIT was being passed to kproc_create.
The result was that shutdown took quite a bit longer because this
errant "child" would not respond to termination signals from init
at system shutdown.
RFNOWAIT dissassociates itself from the caller by attaching to init
as a parent proc. We could have had the taskqueue proc listen for
SIGKILL, but being able to SIGKILL a potentially critical system
process doesn't seem like a good idea.

This manual page was obtained from NetBSD, and the required

Pre-cursor review: joe@
comment about this flag in rev.1.61. It is not historical like the
comment said; it is the flag that says that most of what is laboriously
put in the bootinfo struct is actually there. Newer kernels were
bootable by even the broken boot2 without losing anything except the
symbol table, but older kernels need at least the memory sizes.
Restoring the "|" with RB_BOOTINFO that was lost in rev.1.43 costs 5
bytes. The fix can be done in only 4 bytes by fixing some code that
was removed in rev.1.61 (put RB_BOOTINFO back in in the initial value
of "opts" and fix RBX_MASK to not clobber it.)
crashes that had sn0 as the irq that's being serviced, when there was
no sn0 in the system. This seems to prevent them. Also, we want to
wait until after we've registered with the network layer before we
turn on the interrupt spigot to avoid races.
* Add MLINKS for:
-> Soundblaster emu10k1(4) Driver [points to pcm(4)]
-> Avance Logic ALS400 Driver [points to pcm(4)]
We should not need separate manual page for each of these
drivers; instead, linking them to pcm(4) manual page is
simpler, and new device lists can be easily added to the
said manual page.
* While I am here, sort out mdoc(7) entries in ${MAN}.

do only unlink the file if we could indeed overwrite the file.
Old behaviour: rm -P /tmp/foo (foo mode 0444) would NOT overwrite foo,
but still delete it (with a warning: rm: foo: Permission denied)
New behaviour: Just the EPERM warning, but no deletion

free one sem_undo with un_cnt == 0 instead of all of them. This is a
temporary workaround until the SLIST_FOREACH_PREVPTR loop gets fixed so
that it doesn't cause cycles in semu_list when removing multiple adjacent
items. It might be easier to just use (doubly-linked) LISTs here instead
of complicated SLIST code to achieve O(1) removals.
This bug manifested itself as a complete lockup under heavy semaphore use
by multiple processes with the SEM_UNDO flag set.

Only update them in the newly created context to reflect the state
after copying the dirty registers onto the user stack. If we were to
update the trapframe, we lose the state at entry into the kernel. We
may need that after we create the context, such as for KSE upcalls.
We have to update the trapframe after writing the dirty registers to
the user stack for signal delivery to work. But this is best done in
sendsig() itself where it applies, not in get_mcontext() where it's
done unconditionally.
with debugger, so testing P_TRACED in SIGPENDING is useless. This test also
is the culprit which causes lots of 'failed to set signal flags properly for
ast()' to be printed on console which is just a false complaint.
