Hi,

xfstests cases:
generic/075 generic/112 generic/127 generic/231 generic/263

fail with DAX, pass without it. Both xfs and ext4.

It was okay on 0306 -next tree.

Thanks for the report.  I'm looking into it.  -next is all kinds of broken.
:(

Just FYI, in case folks are still testing -next:

One other issue that I was hitting was that for many of the commits in -next
kernel modules wouldn't load, which meant that my /dev/pmem0 device wasn't
showing up because I have libnvdimm compiled as a module.

I bisected that issue to this commit:

commit d1091c7fa3d5 ("objtool: Improve detection of BUG() and other dead
ends")

It looks like Xiong also found this issue:

And Linus found it:
