[PATCH v4 4/4] writeback: rename nr_reclaimable to nr_dirty in balance_dirty_pages

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit 8d92890bd6b85 ("mm/writeback: discard NR_UNSTABLE_NFS, use
NR_WRITEBACK instead") removed NR_UNSTABLE_NFS and nr_reclaimable
only contains dirty page now.
Rename nr_reclaimable to nr_dirty properly.
