I've also got rid of the bit clearances from the network filesystem evict_inode functions as they doesn't seem to be necessary. Note that the last vestiges of try_to_release_page() got swept away in the current merge window, so I rebased and dealt with that. One comment remained, which is removed by the first patch. David Changes: ======== ver #5) - Rebased on linus/master. try_to_release_page() has now been entirely replaced by filemap_release_folio(), barring one comment. - Cleaned up some pairs in ext4. ver #4) - Split has_private/release call pairs into own patch. - Moved folio_needs_release() to mm/internal.h and removed open-coded version from filemap_release_folio(). - Don't need to clear AS_RELEASE_ALWAYS in ->evict_inode(). - Added experimental patch to reduce shrink_folio_list(). ver #3) - Fixed mapping_clear_release_always() to use clear_bit() not set_bit(). - Moved a '&&' to the correct line. ver #2) - Rewrote entirely according to Willy's suggestion[1].
