The original error had been in v2.6.39 with commit 7eaceaccab5f ("block: remove per-queue plugging"), which replaced conditional plugging by periodic runqueue. Commit 9d1deb83d489 in v4.1-rc1 removed the periodic runqueue and the problem started to manifest. Fixes: 9d1deb83d489 ("dm: don't schedule delayed run of the queue if nothing to do") Signed-off-by: Jun'ichi Nomura Signed-off-by: Mike Snitzer --- Reading git-diff-tree failed
