Subject: [PATCH -mm 4/8] slub: remove kmemcg id from create_unique_id
Date: Mon, 7 Jul 2014 16:00:09 +0400 [thread overview]
Message-ID: <314566c1c65e0d0b391539d828a6c499ca291ef6.1404733720.git.vdavydov@parallels.com> (raw)
In-Reply-To: <cover.1404733720.git.vdavydov@parallels.com>
This function is never called for memcg caches, because they are
unmergeable, so remove the dead code.
Signed-off-by: Vladimir Davydov <vdavydov@parallels.com>
