Subject: [PATCH -mm 1/2] memcg: remove unused mem_cgroup->oom_wakeups
Date: Wed, 3 Jun 2015 11:38:24 +0900 [thread overview]
Message-ID: <20150603023824.GA7579@mtj.duckdns.org> (raw)

Since 4942642080ea ("mm: memcg: handle non-error OOM situations more
gracefully"), nobody uses mem_cgroup->oom_wakeups. Remove it.
