Hello DAX maintainers,
I noticed our PPC64LE builds failing last night:
https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/388047043
https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/388047056
https://travis-ci.com/github/ClangBuiltLinux/continuous-integration/jobs/388047099
and looking on lore, I see a fresh report from KernelCI against arm:
https://lore.kernel.org/linux-next/?q=dax_supported
Can you all please take a look? More concerning is that I see this
failure on mainline. It may be interesting to consider how this was
not spotted on -next.

Thanks,

The failure is fixed with commit 88b67edd7247 ("dax: Fix compilation
for CONFIG_DAX && !CONFIG_FS_DAX"). I rushed the fixes that led to
this regression with insufficient exposure because it was crashing all
users. I thought the 2 kbuild-robot reports I squashed covered all the
config combinations, but there was a straggling report after I sent my
-rc6 pull request.
The baseline process escape for all of this was allowing a unit test
triggerable insta-crash upstream in the first instance necessitating
an urgent fix.

No worries; just checking that failures are root-caused. I see it on
top of v5.9-rc6:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/.
I don't see it on -next today, but assume it will be there tomorrow.
Thanks for the info.
