[PATCHSET v2 cgroup/for-3.16] cgroup: post unified hierarchy fixes and updates

[Tejun Heo]

Hello,

Changes from the last take[L] are,

* 0002, 0003 and 0007 added.

* Other patches are refreshed without content change.

This patchset contains the following seven patches.

 0001-cgroup-fix-offlining-child-waiting-in-cgroup_subtree.patch
 0002-cgroup-cgroup_idr_lock-should-be-bh.patch
 0003-cgroup-css_release-shouldn-t-clear-cgroup-subsys.patch
 0004-cgroup-update-and-fix-parsing-of-cgroup.subtree_cont.patch
 0005-cgroup-use-restart_syscall-for-retries-after-offline.patch
 0006-cgroup-use-release_agent_path_lock-in-cgroup_release.patch
 0007-cgroup-rename-css_tryget-to-css_tryget_online.patch

0001 fixes two bugs in cgroup_subtree_control_write().

0004 fixes and makes subtree_control parsing stricter.

0005 simplifies cgroup_substree_control_write() retry path by using
restart_syscall().

0006 makes cgroup_release_agent_show() use release_path_lock.  The
original conversion missed this one.

0007 renames css_tryget() to css_tryget_online().  This patch was
posted separately before - [1] - and acked by Michal and Johannes.
