Peter Zijlstra 2eab0c7176 sched/cgroup: Fix cgroup entity load tracking tear-down ... When a cgroup's CPU runqueue is destroyed, it should remove its remaining load accounting from its parent cgroup. The current site for doing so it unsuited because its far too late and unordered against other cgroup removal (->css_free() will be, but we're also in an RCU callback). Put it in the ->css_offline() callback, which is the start of cgroup destruction, right after the group has been made unavailable to userspace. The ->css_offline() callbacks are called in hierarchical order after the following v4.4 commit: aa226ff4a1ce ("cgroup: make sure a parent css isn't offlined before its children") Change-Id: Ice7cbd71d9e545da84d61686aa46c7213607bb9d Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Cc: Christian Borntraeger <borntraeger@de.ibm.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Li Zefan <lizefan@huawei.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Oleg Nesterov <oleg@redhat.com> Cc: Paul E.
