One noteable difference is filemap_get_folios_tag() does not take in a maximum pages argument. It instead tries to fill a folio batch and stops either once full (15 folios) or reaching the end of the search range. The new function supports large folios, the initial function did not since all callers don't use large folios.

This is in preparation for the removal of find_get_pages_range_tag(). This change does NOT support large folios. This shouldn't be an issue as of now since ceph only utilizes folios of size 1 anyways, and there is a lot of work to be done on ceph conversions to folios for later patches at some point. Also some minor renaming for consistency.

This is in preparation for the removal of find_get_pages_range_tag(). Also modified f2fs_all_cluster_page_ready to take in a folio_batch instead of pagevec. This does NOT support large folios. The function currently only utilizes folios of size 1 so this shouldn't cause any issues right now.

This is in preparation for the removal of find_get_pages_range_tag(). Initially the function was checking if the previous page index is truly the previous page i.e. 1 index behind the current page. To convert to folios and maintain this check we need to make the check folio->index != prev + folio_nr_pages(previous folio) since we don't know how many pages are in a folio. At index i == 0 the check is guaranteed to succeed, so to workaround indexing bounds we can simply ignore the check for that specific index. This makes the initial assignment of prev trivial, so I removed that as well. Also modified a comment in commit_checkpoint for consistency.
