From d13dfae3cedd60072d448b7e382c86143a29cedc Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 1 Aug 2019 13:13:51 +0200 Subject: [PATCH] crypto: engine - Reduce default RT priority The crypto engine initializes its kworker thread to FIFO-99 (when requesting RT priority), reduce this to FIFO-50. FIFO-99 is the very highest priority available to SCHED_FIFO and it not a suitable default; it would indicate the crypto work is the most important work on the machine. Cc: Herbert Xu Cc: "David S.
