From 0030c1d4a38757fb54a0c96e5e8b59cc0c4f3f28 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 21 Apr 2020 12:09:13 +0200 Subject: [PATCH] sched,bL_switcher: 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. In this case, use fifo_low, because it only cares about being above SCHED_NORMAL. Effectively no change in behaviour.
