Subject: mm: convert page_swap_flags to folio_swap_flags
X-Git-Tag: v6.6.17~6873^2~186
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b98c359f1d921deae04bb5dbbbbbb9d8705b7c4c;p=platform%2Fkernel%2Flinux-rpi.git

mm: convert page_swap_flags to folio_swap_flags

The only caller already has a folio, so push the folio->page conversion
down a level.
