-Use sched_set_fifo on newer kernels
-
-The 5.9 kernel removed the export of sched_setscheduler, use
-the new sched_set_fifo API if building on 5.9 or newer.  There
-is a slight difference in resulting priority level, the new
-API will yield a priority of 50 instead of the explicit value
-of 40 being used with sched_setscheduler, but this should not
-be an issue.
