[PATCH RFC 07/14] fs/dax: use vmf_insert_folio_pmd() to insert the huge zero folio

Let's convert to vmf_insert_folio_pmd(). In the unlikely case there is already something mapped, we'll now still call trace_dax_pmd_load_hole() and return VM_FAULT_NOPAGE. That should probably be fine, no need to add special cases for that. Signed-off-by: David Hildenbrand --- fs/dax.c | 47 ++
