Subject: shmem: convert shmem_alloc_hugepage() to use vma_alloc_folio()
Patch series "Folio patches for 5.19".
- Finish the conversion from alloc_pages_vma() to vma_alloc_folio()
- Finish converting shrink_page_list() to folios
- Start converting shmem from pages to folios (alas, not finished,
I have simply run out of time with all the debugging/fixing needed
for 5.18)
This patch (of 21):
For now, return the head page of the folio, but remove use of the old
alloc_pages_vma() API.
