Subject: [PATCH v9 10/17] From: Kirill Tkhai <ktkhai@virtuozzo.com>
Date: Mon, 09 Jul 2018 11:39:04 +0300 [thread overview]
Message-ID: <153112554453.4097.12367687920458389659.stgit@localhost.localdomain> (raw)
In-Reply-To: <153112469064.4097.2581798353485457328.stgit@localhost.localdomain>
list_lru: Pass dst_memcg argument to memcg_drain_list_lru_node()
This is just refactoring to allow next patches to have
dst_memcg pointer in memcg_drain_list_lru_node().
