The code can reverse assignments but I would have some preference for keeping higher numeric value to be higher priority. - it is more natural for compare - POSIX keeps that notation [pthread_setschedprio](https://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_setschedprio.html) - the applications and services which do not set the priority or use zero should be low priority by default to not cause link level priority inversion for high priority classes by uncontrolled sending of low priority CAN ID message (yes in this case high numeric value) -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/49#note_108445 You're receiving this email because of your account on gitlab.rtems.org.
