The following commit has been merged into the sched/fifo branch of tip: Commit-ID: 28d2f209cd1620afaca6d0a61d1e88a269e9e875 Gitweb: https://git.kernel.org/tip/28d2f209cd1620afaca6d0a61d1e88a269e9e875 Author: Peter Zijlstra <peterz@xxxxxxxxxxxxx> AuthorDate: Tue, 21 Apr 2020 12:09:13 +02:00 Committer: Peter Zijlstra <peterz@xxxxxxxxxxxxx> CommitterDate: Mon, 15 Jun 2020 14:10:23 +02:00 sched,serial: 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. Effectively no change.
