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

[Tejun Heo]

Hello,

This patchset contains the following four patches.

 0001-cgroup-fix-offlining-child-waiting-in-cgroup_subtree.patch
 0002-cgroup-only-allow-space-as-the-separator-for-cgroup..patch
 0003-cgroup-use-restart_syscall-for-retries-after-offline.patch
 0004-cgroup-use-release_agent_path_lock-in-cgroup_release.patch

0001 fixes two bugs in cgroup_subtree_control_write().

0002 makes subtree_control parsing stricter.

0003 simplifies cgroup_substree_control_write() retry path by using
restart_syscall().

0004 makes cgroup_release_agent_show() use release_path_lock.  The
original conversion missed this one.

This patchset is on top of cgroup/for-3.16 12d3089c192c
("kernel/cpuset.c: convert printk to pr_foo()") and available on the
following git branch.

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup.git review-post-unified-updates
