++ * cgroup_attach_lock - Lock for ->attach()
++ * @lock_threadgroup: whether to down_write cgroup_threadgroup_rwsem
++ *
++ * cgroup migration sometimes needs to stabilize threadgroups against forks and
++ * exits by write-locking cgroup_threadgroup_rwsem. However, some ->attach()
++ * implementations (e.g. cpuset), also need to disable CPU hotplug.
++ * Unfortunately, letting ->attach() operations acquire cpus_read_lock() can
++ * lead to deadlocks.
++ *
++ * Bringing up a CPU may involve creating and destroying tasks which requires
++ * read-locking threadgroup_rwsem, so threadgroup_rwsem nests inside
++ * cpus_read_lock(). If we call an ->attach() which acquires the cpus lock while
++ * write-locking threadgroup_rwsem, the locking order is reversed and we end up
++ * waiting for an on-going CPU hotplug operation which in turn is waiting for
++ * the threadgroup_rwsem to be released to create new tasks. For more details:
