This reverts commit 5735a2671ffb70ea29ca83969fe01316ee2ed6fc which is commit 0a9bab391e336489169b95cb0d4553d921302189 upstream.
Tasklet is thought to cause memory corruption [1], so it was disabled in dm-crypt and dm-verity. However, memory corruption may not happen since cc->io_queue is created without WQ_UNBOUND [2]. Revert commit 5735a2671ffb ("dm-crypt, dm-verity: disable tasklets") to bring tasklet back.
