I was chasing the following kselftest issue:

  Testing move-pmd on anon... ERROR: nr 6144 move failed 5332351020490051840 1
   (errno=17, @linux/tools/testing/selftests/mm/uffd-unit-tests.c:1198)

... and ended up bisecting to adfb6609c680 ("mm/huge_memory: initialise
the tags of the huge zero folio") too.

FWIW, your patch fixed the failures. I'm running an x86_64 image on
crosvm.
