+
+ * bits/sched.h: Remove __need_schedparam logic and replace with a
+ normal multiple-include guard. Change field name in struct
+ sched_param from __sched_priority to sched_priority. Delete
+ everything under #ifndef __cpu_set_t_defined.
+ * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with
+ kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants.
+
+ * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h.
+ For compatibility, #define sched_priority to itself, and #define
+ __sched_priority as sched_priority.
+ * posix/bits/cpu-set.h: New file containing, verbatim, the code
+ that was under #ifndef __cpu_set_t_defined in
+ sysdeps/unix/sysv/linux/bits/sched.h.
+ * include/bits/cpu-set.h: New wrapper.
+ * posix/Makefile: Install bits/cpu-set.h.
