From dbc6d0d5a5467adb6ea5fb25844e471c7bf8fabf Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 21 Apr 2020 12:09:13 +0200 Subject: sched,crypto: Convert to sched_set_fifo*() Because SCHED_FIFO is a broken scheduler model (see previous patches) take away the priority field, the kernel can't possibly make an informed decision. Use sched_set_fifo() to request SCHED_FIFO and delegate actual priority selection to userspace. Effectively no change in behaviour.
