    Hi, Shaggy,

    I'm finally getting around to testing this using xfstests. This is my
    setup:

    dd if=/dev/zero of=testdev.img bs=1M count=1024
    dd if=/dev/zero of=scratchdev.img bs=1M count=1024
    losetup -f ./testdev.img
    losetup -f ./scratchdev.img
    mkfs -t xfs /dev/loop0
    mount /dev/loop0 /mnt/test
    export TEST_DIR=/mnt/test
    export TEST_DEV=/dev/loop0
    export SCRATCH_MNT=/mnt/scratch
    export SCRATCH_DEV=/dev/loop1

    I then ran:

    ./check -g aio

    and here is the summary:

    Ran: 112 113 198 207 208 209 210 211 212 239 240
    Failures: 112 198 207 239 240
    Failed 5 of 11 tests

    To be fair, I have not yet run this on a kernel without your changes.
    I'm going to do that next, but wanted to give you a heads-up, in case
    you had time to dig into the failures. Let me know if you want the full
    output from the run, but I assume you'll want to reproduce this anyway.

    Oh, I pulled your git branch into a 3.8.0-rc4 kernel tree, FYI.

    Cheers,
    Jeff
