Hi,
FIBMAP ioctl call to file in pmem dax mountpoint, both xfs
and ext4, starts to fail on v4.17-rc1 Linus tree.
+fibmap: Invalid argument
Pass on v4.16.
Pass on non-dax mountpoint.
We got these in v4.17-rc1:
6e2608d xfs, dax: introduce xfs_dax_aops
fb094c9 ext2, dax: introduce ext2_dax_aops

Hi,
xfstests cases:

Hi,
LTP tests on DAX show 2 issues.
msync03 and diotest4, both xfs and ext4,
non-DAX pass
DAX fail
1, MAP_LOCKED && msync with MS_INVALIDATE, which should fail.
Flag checking code in msync looks ok but missing _LOCK vma falgs
for DAX mapped vma ? i guess DAX now does not support that ?

Hi lists,
Since around 20161129 tag, LTP rwtest01 on dax mountpoint blocks
on linux-next tree, now on Linus tree.
In "normal", rwtest01 subcase ends in a few minutes, now it keeps
running for hours on dax mountpoint, both ext4 and xfs. Ctrl + c
can interrupt it.
It is always reproducible, blocki
