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+.
