I'm going through my patch queue implementing peterz's request to rename FolioUptodate() as folio_uptodate(). It's going pretty well, but it throws into relief all the places where we're not consistent naming existing functions which operate on pages as page_foo(). The folio conversion is a great opportunity to sort that out. Mostly so far, I've just done s/page/folio/ on function names, but there's the opportunity to regularise a lot of them, eg: put_page folio_put lock_page folio_lock lock_page_or_retry folio_lock_or_retry rotate_reclaimable_page folio_rotate_reclaimable end_page_writeback folio_end_writeback clear_page_dirty_for_io folio_clear_dirty_for_io Some of these make a lot of sense -- eg when ClearPageDirty has turned into folio_clear_dirty(), having folio_clear_dirty_for_io() looks regular. I'm not entirely convinced about folio_lock(), but folio_lock_or_retry() makes more sense than lock_page_or_retry(). Ditto _killable() or _async(). Thoughts?
