cgroup: deprecate remount option changes
This patch marks the following features for deprecation. * Rebinding subsys by remount: Never reached useful state - only works on empty hierarchies. * release_agent update by remount: release_agent itself will be replaced with conventional fsnotify notification. v2: Lennart pointed out that "name=" is necessary for mounts w/o any controller attached. Drop "name=" deprecation. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizf@cn.fujitsu.com> Cc: Lennart Poettering <mzxreary@0pointer.de>

of ASLR. It was only ever intended for debugging, so it should be
removed.

+What: cgroup option updates via remount
+When: March 2013
+Why: Remount currently allows changing bound subsystems and
+ release_agent. Rebinding is hardly useful as it only works
+ when the hierarchy is empty and release_agent itself should be
+ replaced with conventional fsnotify.
