[PATCH 5/6] writeback: rename nr_reclaimable to nr_dirty in balance_dirty_pages

From: Kemeng Shi
Date: Tue Mar 19 2024 - 22:08:28 EST


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.
