mm: vmscan: filter out the dirty file folios for node_reclaim()
Patch series "optimize the logic for handling dirty file folios during
reclaim", v2.
Since we no longer attempt to write back filesystem folios during reclaim,
some logic for handling dirty file folios in the reclaim process also
needs to be updated. Please check the details in each patch.
This patch (of 2):
After commit 6b0dfabb3555 ("fs: Remove aops->writepage"), we no longer
attempt to write back filesystem folios in pageout(), and only tmpfs/shmem
folios and anonymous swapcache folios can be written back. Therefore, we
should also filter out the dirty filesystem folios for node_reclaim() to
avoid unnecessary LRU scans.
