Date: Fri, 14 Dec 2012 14:41:14 -0800 From: Tejun Heo <tj@...nel.org> To: lizefan@...wei.com, axboe@...nel.dk, vgoyal@...hat.com Cc: containers@...ts.linux-foundation.org, cgroups@...r.kernel.org, linux-kernel@...r.kernel.org, ctalbott@...gle.com, rni@...gle.com, Tejun Heo <tj@...nel.org> Subject: [PATCH 01/12] blkcg: fix minor bug in blkg_alloc() blkg_alloc() was mistakenly checking blkcg_policy_enabled() twice. The latter test should have been on whether pol->pd_init_fn() exists. This doesn't cause actual problems because both blkcg policies implement pol->pd_init_fn(). Fix it.
