+        This aligns bits/sched.h onto sysdeps/unix/sysv/linux/bits/sched.h:
+        Define __sched_param instead of SCHED_* and sched_param when
+       <bits/sched.h> is included with __need_schedparam defined.
+        * bits/sched.h [__need_schedparam]
+       (SCHED_OTHER, SCHED_FIFO, SCHED_RR, sched_param): Do not define.
+        [!__defined_schedparam && (__need_schedparam || _SCHED_H)]
+        (__defined_schedparam): Define to 1.
+       (__sched_param): New structure, identical to sched_param.
+       (__need_schedparam): Undefine.

        * sysdeps/unix/sysv/linux/sparc/sys/epoll.h (epoll_create2): Delete.
