The patch titled
Subject: cma: decrease cc.nr_migratepages after reclaiming pagelist
has been removed from the -mm tree. Its filename was
cma-decrease-ccnr_migratepages-after-reclaiming-pagelist.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Minchan Kim <minchan@xxxxxxxxxx>
Subject: cma: decrease cc.nr_migratepages after reclaiming pagelist
reclaim_clean_pages_from_list() reclaims clean pages before migration so
cc.nr_migratepages should be updated. Currently, there is no problem but
it can be wrong if we try to use the value in future.
