c3aab9a0bd91 ("mm/filemap.c: don't initiate writeback if mapping has
no dirty pages") likely addresses larger part of the problem, but yeah
it prolly makes sense to backport both for -stable.
Greg, Sasha, can you pick the following two commits for -stable?
* c3aab9a0bd91 ("mm/filemap.c: don't initiate writeback if mapping has
no dirty pages")
* 65de03e25138 ("cgroup,writeback: don't switch wbs immediately on
dead wbs if the memcg is dead")
Both are fixes for e8a7abf5a5bd ("writeback: disassociate inodes from
dying bdi_writebacks") - v4.2+.
Thanks.
