----------------------------------------------------------------

 - Fix a "BUG: kernel NULL pointer dereference" issue due to
   inconsistent on-disk indices of compressed inodes against
   per-sb `available_compr_algs` generated by Syzkaller;

 - Don't use certain unnecessary folio_*() helpers if the folio
   type (page cache) is known.
