Modified files:
sys/kern vfs_aio.c
Log:
In aio_waitcomplete, do not return EAGAIN if no other threads
have started aio, instead, initialize aio management structure
if it hasn't been done, the reason to adjust this behavior is
to make it a bit friendly for threaded program, consider two
threads, one submits aio_write, and another just calls
aio_waitcomplete to wait any I/O to be completed and recycle the
aio requests, before submitter doing any I/O, the recycler wants
to wait in kernel. This also fixes inconsistency with other aio
syscalls.
