+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.
