2021-06-10	Fix lock ordering issue when enumerating cgroup tasks.	Rahat Mahmood
	The control files enumerating tasks and threads residing in cgroupfs incorrectly locks cgroupfs.filesystem.tasksMu before kernel.TaskSet.mu. The contents of these control files are inherently racy anyways, so use a snapshot of the tasks in the cgroup and drop tasksMu before resolving pids/tids (which acquires TaskSet.mu).

2021-05-14	Fix cgroup hierarchy registration.	Rahat Mahmood
	Previously, registration was racy because we were publishing hierarchies in the registry without fully initializing the underlying filesystem. This led to concurrent mount(2)s discovering the partially intialized filesystems and dropping the final refs on them which cause them to be freed prematurely.
