Subject: f2fs: convert f2fs_fsync_node_pages() to use filemap_get_folios_tag()
X-Git-Tag: v6.6.17~5460^2~256
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e6e46e1eb7cea179b9b31a62a0bbac6ba24bd050;p=platform%2Fkernel%2Flinux-rpi.git

f2fs: convert f2fs_fsync_node_pages() to use filemap_get_folios_tag()

Convert function to use a folio_batch instead of pagevec.  This is in
preparation for the removal of find_get_pages_range_tag().
