Change Details

Processes with realtime privilege may promote existing threads and processes to realtime scheduling priority. Extend this privilege to allow explicit creation of new realtime threads. One use case of this is when the pthread scheduling policy is set to `SCHED_RR` or `SCHED_FIFO` via `pthread_attr_setschedpolicy(...)` before calling `pthread_create(...)`. I ran into this when testing audio software with realtime threads, particularly `audio/ardour6`.

With the mac_priority(4) realtime policy active, users and processes in the realtime group may promote existing threads and processes to realtime scheduling priority. Extend the privileges granted to `PRIV_SCHED_SETPOLICY` which allows explicit creation of new realtime threads. One use case of this is when the pthread scheduling policy is set to `SCHED_RR` or `SCHED_FIFO` via `pthread_attr_setschedpolicy(...)` before calling `pthread_create(...)`.
