Andrew,

Here is the fix to this AIO oops. An AIO O_DIRECT request was extending
the file so it was done synchronously. However, the request got an
EFAULT and direct_io_worker() was calling aio_complete() on the iocb and
returning the EFAULT. When io_submit_one() got the EFAULT return,
it assume it had to call aio_complete() since the i/o never got
queued.

The fix is for direct_io_worker() to only call aio_complete() when
the upper layer is going to return -EIOCBQUEUED and not when getting
errors that are being return to the submit path.

This also applies to 2.6.4-rc1-mm2.
