The patch titled
Subject: memcg: remove unused mem_cgroup->oom_wakeups
has been removed from the -mm tree. Its filename was
memcg-remove-unused-mem_cgroup-oom_wakeups.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Tejun Heo <tj@xxxxxxxxxx>
Subject: memcg: remove unused mem_cgroup->oom_wakeups
Since 4942642080ea ("mm: memcg: handle non-error OOM situations more
gracefully"), nobody uses mem_cgroup->oom_wakeups. Remove it.
While at it, also fold memcg_wakeup_oom() into memcg_oom_recover() which
is its only user. This cleanup was suggested by Michal.
