[PATCH 0/2] some cleanups for pageout()

[Baolin Wang <baolin.wang@linux.alibaba.com>]

Since we no longer attempt to write back filesystem folios in pageout(),
and only tmpfs/shmem folios and anonymous swapcache folios can be written
back, we can remove the redundant folio_test_private() related logic to
simplify the logic of pageout(), as tmpfs/shmem and swapcache folios do
not use the PG_private flag.

Baolin Wang (2):
  mm: vmscan: remove folio_test_private() check in pageout()
  mm: vmscan: simplify the folio refcount check in pageout()
