From 0b7a1e0d3463aa8aa4b7dcad0ec154e658d68036 Mon Sep 17 00:00:00 2001
From: Kurt Kanzenbach <kurt@kmk-computers.de>
Date: Wed, 1 Apr 2020 20:15:24 +0200
Subject: [PATCH] all: Fix musl build
There are a few problems:
* pi stress: pthread_attr_setaffinity_np() is not supported
* cyclictest: SIGEV_THREAD_ID is not supported
* hackbench: Fix include, add missing casts
* all: Fix sched_* calls
With these changes applied, the rt-tests seem to run fine.
