It's possible to remove a big chunk of the redundant code by making
memcg_flush_offline_percpu() to take cpumask as an argument and flush
percpu data on all cpus belonging to the mask instead of all possible cpus.
Then memcg_hotplug_cpu_dead() can call it with a single CPU bit set.
This approach

A cgroup can remain in the dying state for a long time, being pinned in the
memory by any kernel object. It can be pinned by a page, shared with other

Although per-cpu stats are never exactly precise, dropping them on

safer to flush them before releasing.

Similar to the memcg's vmstats_percpu, per-memcg per-node stats

that both coexist during the whole life-cycle of the memcg.
