Subject: [PATCH v9 11/17] list_lru: Pass lru argument to memcg_drain_list_lru_node()
Date: Mon, 09 Jul 2018 11:39:16 +0300
Message-ID: <153112555610.4097.2305461097830154246.stgit@localhost.localdomain> (raw)
In-Reply-To: <153112469064.4097.2581798353485457328.stgit@localhost.localdomain>

This is just refactoring to allow next patches to have
lru pointer in memcg_drain_list_lru_node().
