The patch titled
Subject: mm: memcontrol: replace mem_cgroup_lruvec_online with mem_cgroup_online
has been removed from the -mm tree. Its filename was
mm-memcontrol-replace-mem_cgroup_lruvec_online-with-mem_cgroup_online.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx>
Subject: mm: memcontrol: replace mem_cgroup_lruvec_online with mem_cgroup_online
mem_cgroup_lruvec_online() takes lruvec, but it only needs memcg. Since
get_scan_count(), which is the only user of this function, now possesses
pointer to memcg, let's pass memcg directly to mem_cgroup_online() instead
of picking it out of lruvec and rename the function accordingly.
