-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
- * all:        Fix sched_* calls
-
-With these changes applied, the rt-tests seem to run fine.
