8a22e151be As a result of kqueue locking work, socket buffer locks will always
be held when entering a kqueue filter for fifos via a socket buffer
event: as such, assert the lock unconditionally rather than acquiring
it conditionall.

db7a6c2f43 Annotate two issues:
1) fifo_kqfilter() is not actually ever used, it likely should be GC'd.

2) fifo_kqfilter_f() doesn't implement EVFILT_VNODE, so detecting events
   on the underlying vnode for a fifo no longer works (it did in 4.x).
   Likely, fifo_kqfilter_f() should forward the request to the VFS using
   fp->f_vnode, which would work once fifo_kqfilter() was detached from
   the vnode operation vector (removing the fifo override).

88f39e8e95 Introduce no-op nosup fifo kqueue filter and detach routine, which are
used when a read filter is requested on a write-only fifo descriptor, or
a write filter is requested on a read-only fifo descriptor.  This
permits the filters to be registered, but never raises the event, which
causes kqueue behavior for fifos to more closely match similar semantics
for poll and select, which permit testing for the condition even though
the condition will never be raised, and is consistent with POSIX's notion
that a fifo has identical semantics to a one-way IPC channel created
using pipe() on most operating systems.

The fifo regression test suite can now run to completion on HEAD without
errors.

831a62e7e5 - Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).
- Remove an assertion in sound.c, it's not needed (and causes a panic now).
  From the conversation via mail between glebius and Ariff:
  ---snip---
  > Well, but which mutex protects now? Do we own anything else
  > in pcm_chnalloc()? I see some queue(4) macros in pcm_chnalloc(),
  > they should be protected, shouldn't they?
  Queue insertion/removal occur during
     1) driver loading (which is pretty much single thread /
        sequential) or unloading (mutex protected, bail out if there is
        any channel with refcount > 0 or busy).
     2) vchan_create()/destroy(), (which is *sigh* quite complicated), but
        somehow protected by 'master'/parent channel mutex. Other
        thread cannot add/remove vchan (or even continue traversing
        that queue) unless it can acquire parent channel mutex.
---snip---

Fix the locking in dsp.c to prevent a LOR (AFAIK not on the LOR page).

114538d85b Remove DFLAG_SEEKABLE from fifo file descriptors: fifos are not seekable
according to POSIX, not to mention the fact that it doesn't make sense
(and hence isn't really implemented).  This causes the fifo_misc
regression test to succeed.

6dd84b0bdc Only poll the fifo for read events if the fifo is attached to a readable
file descriptor.  Otherwise, the read end of a fifo might return that it
is writable (which it isn't).

Only poll the fifo for write events if the fifo attached to a writable
file descriptor.  Otherwise, the write end of a fifo might return that
it is readable (which it isn't).

In the event that a file is FREAD|FWRITE (which is allowed by POSIX, but
has undefined behavior), we poll for both.

845e8e827b After going to some trouble to identify only the write-related events
to poll the write socket for, the fifo polling code proceeded to poll
for the complete set of events.  Use 'levents' instead of 'events' as
the argument to poll, and only poll the write socket if there is
interest in write events.
