Hi,
The generic/617 of fstests is a test case does IO_URING soak direct-IO
fsx test, but recently (about from v6.6-rc1 to now) it always fails on
overlayfs as [1], no matter the underlying fs is ext4 or xfs. But it
never failed on overlay before, likes [2].
So I thought it might be a regression of overlay or io-uring on current v6.6.
Please help to review, it's easy to reproduce. My system is Fedora-rawhide/RHEL-9,
with upstream mainline linux HEAD=dc912ba91b7e2fa74650a0fc22cccf0e0d50f371.
The generic/617.full output as [3].
Thanks,
Zorro

Hi Zorro,
Thank you for the report.
I am on public holiday, so it may take me a few days to get to look at this.
In the meanwhile could you try to bisect if the regression is introduced
by this vfs PR merge (of my patches):
* de16588a7737 - Merge tag 'v6.6-vfs.misc' of
git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
|\
| * e6fa4c728fb6 - cachefiles: use kiocb_{start,end}_write() helpers
| * 8f7371268a4b - ovl: use kiocb_{start,end}_write() helpers
| * 8c3cfa80fd1e - aio: use kiocb_{start,end}_write() helpers
| * e484fd73f4bd - io_uring: use kiocb_{start,end}_write() helpers
The io_uring PR merge:
* c1b7fcf3f6d9 - Merge tag 'for-6.6/io_uring-2023-08-28' of
git://git.kernel.dk/linux
Or the overlayfs PR merge:
* 63580f669d7f - Merge tag 'ovl-update-6.6' of
git://git.kernel.org/pub/scm/linux/kernel/git/overlayfs/vfs
Thanks,
Amir.

It works without overlayfs - would be great if you could include how to
reproduce this with overlayfs.

Try this. Certainly looks like this could be the issue, overlayfs is
copying the flags but it doesn't handle IOCB_DIO_CALLER_COMP. So it
either needs to handle that, or just disabled it. Seems like the latter
is the easier/saner solution here, which is what the below does.

Sorry I didn't provide the test steps:
1) git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git
2) cd xfstests-dev
3) make -j8 # refer to README, about how to build xfstests
4) vi local.config
# The FSTYP can be other fs, e.g. ext4.
# The TEST_DEV and SCRATCH_DEV can be any local devices you have (even loopdev)
# TEST_DIR and SCRATCH_MNT can be changed too
export FSTYP=xfs
export TEST_DEV=/dev/sda5
export TEST_DIR=/mnt/test
export SCRATCH_DEV=/dev/sda3
export SCRATCH_MNT=/mnt/scratch
5) mkfs.xfs -f /dev/sda5 && mkfs.xfs -f /dev/sda3
6) mkdir -p /mnt/test && mkdir -p /mnt/scratch
7) ./check -overlay generic/617
The step#6 will be failed.
Thanks,
Zorro
