Date: Fri, 16 Mar 2012 16:35:54 -0700 From: Tejun Heo <tj@...nel.org> To: glommer@...allels.com, lizf@...fujitsu.com, containers@...ts.linux-foundation.org, cgroups@...r.kernel.org Cc: linux-kernel@...r.kernel.org, fweisbec@...il.com, rni@...gle.com, ctalbott@...gle.com, Tejun Heo <tj@...nel.org> Subject: [PATCH 01/10] cgroup: move cgroup_clear_directory() call out of cgroup_populate_dir() cgroup_populate_dir() currently clears all files and then repopulate the directory; however, the clearing part is only useful when it's called from cgroup_remount(). Relocate the invocation to cgroup_remount(). This is to prepare for further cgroup file handling updates.
