And struct sched_attr. In sysdeps/unix/sysv/linux/bits/sched.h, the hack that defines sched_param around the inclusion of <linux/sched/types.h> is quite ugly, but the definition of struct sched_param has already been dropped by the kernel, so there is nothing else we can do and maintain compatibility of <sched.h> with a wide range of kernel header versions. (An alternative would involve introducing a separate header for this functionality, but this seems unnecessary.) The existing sched_* functions that change scheduler parameters are already incompatible with PTHREAD_PRIO_PROTECT mutexes, so there is no harm in adding more functionality in this area. The documentation mostly defers to the Linux manual pages. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
