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
