dm crypt: use WQ_HIGHPRI for the IO and crypt workqueues Running dm-crypt with workqueues at the standard priority results in IO competing for CPU time with standard user apps, which can lead to pipeline bubbles and seriously degraded performance. Move to using WQ_HIGHPRI workqueues to protect against that.
