Ben,

aio_read/aio_write() are now working with a minor fix to fs/aio.c

io_submit_one():

if (likely(EIOCBQUEUED == ret))

needs to be changed to

if (likely(-EIOCBQUEUED == ret))
^^^

I was wondering what happens to following case (I think this
happend in my test program).

Lets say, I did an sys_io_submit() and my test program did exit().
When the IO complete happend, it tried to do following and got
an OOPS in aio_complete().

if (ctx == &ctx->mm->default_kioctx) {

I think "mm" is freed up, when process exited. Do you think this is
possible ? How do we handle this ?
