Sorry, I sent the list below to Chandan, didn't cc the maillist
because it's just a rough list rather than a PR:
1. subject: [v3] xfs: correct calculation for agend and blockcount
url:
https://lore.kernel.org/linux-xfs/20230913102942.601271-1-ruansy.fnst@xxxxxxxxxxx/
note: This one is a fix patch for commit: 5cf32f63b0f4 ("xfs:
fix the calculation for "end" and "length"").
It can solve the fail of xfs/55[0-2]: the programs
accessing the DAX file may not be notified as expected,
because the length always 1 block less than actual. Then
this patch fixes this.
2. subject: [v15] mm, pmem, xfs: Introduce MF_MEM_PRE_REMOVE for unbind
url:
https://lore.kernel.org/linux-xfs/20230928103227.250550-1-ruansy.fnst@xxxxxxxxxxx/T/#u
note: This is a feature patch. It handles the pre-remove event
of DAX device, by notifying kernel/user space before actually
removing.
It has been picked by Andrew in his
mm-hotfixes-unstable. I am not sure whether you or he will
merge this one.
3. subject: [v1] xfs: drop experimental warning for FSDAX
url:
https://lore.kernel.org/linux-xfs/20230915063854.1784918-1-ruansy.fnst@xxxxxxxxxxx/
note: With the patches mentioned above, I did a lot of tests,
including xfstests and blackbox tests, the FSDAX function looks
good now. So I think the experimental warning could be dropped.
Darrick/Dave, Could you please review the above patch and let us know if you
have any objections?
The first two patches are ok. The third one ... well I was about to say
ok but then this happened with generic/269 on a 6.6-rc4 kernel and those
two patches applied:
Hi Darrick,
Thanks for testing. I just tested this case (generic/269) on v6.6-rc4
with my 3 patches again, but it didn't fail. Such WARNING message
didn't show in dmesg too.
My local.config is shown as below:
[nodax_reflink]
export FSTYP=xfs
export TEST_DEV=/dev/pmem0
export TEST_DIR=/mnt/test
export SCRATCH_DEV=/dev/pmem1
export SCRATCH_MNT=/mnt/scratch
export MKFS_OPTIONS="-m reflink=1,rmapbt=1"
[dax_reflink]
export FSTYP=xfs
export TEST_DEV=/dev/pmem0
export TEST_DIR=/mnt/test
export SCRATCH_DEV=/dev/pmem1
export SCRATCH_MNT=/mnt/scratch
export MKFS_OPTIONS="-m reflink=1,rmapbt=1"
export MOUNT_OPTIONS="-o dax"
export TEST_FS_MOUNT_OPTS="-o dax"
And tools version are:
- xfstests (v2023.09.03)
- xfsprogs (v6.4.0)
Could you show me more info (such as kernel config, local.config) ? So
that I can find out what exactly is going wrong.

Ruan.
