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.
