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:
I don't see it on -next today, but assume it will be there tomorrow.
Thanks for the info.
