Modified files:
sys/kern vfs_aio.c
Log:
1. Remove aio entry from lists earlier in aio_free_entry,
so other threads can not see it if we unlock the proc
lock (this can happen in knlist_delete). Don't do wakeup,
it is not necessary.
2. Decrease kaio_buffer_count in biohelper rather than
doing it in aio_bio_done_notify.
3. In aio_bio_done_notify, don't send notification if KAIO_RUNDOWN
was set, because the process is already in single thread mode.
4. Use assignment to initialize aiothreadflags.
5. AIOCBLIST_RUNDOWN is not useful, axe the code using it.
6. use LIO_NOP instead of zero.
