userfaultfd: convert mfill_atomic_pte_copy() to use a folio
Patch series "userfaultfd: convert userfaultfd functions to use folios",
v6.
This patch series converts several userfaultfd functions to use folios.
This patch (of 6):
Call vma_alloc_folio() directly instead of alloc_page_vma() and convert
page_kaddr to kaddr in mfill_atomic_pte_copy(). Removes several calls to
compound_head().
