    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.
