cgroup: use restart_syscall() for retries after offline waits in cgroup_subtree_control_write() After waiting for a child to finish offline, cgroup_subtree_control_write() jumps up to retry from after the input parsing and active protection breaking. This retry makes the scheduled locking update more difficult. Let's simplify it by returning with restart_syscall() for retries. Signed-off-by: Tejun Heo <tj@kernel.org>
