 Applied, thanks.
 
 I have also added a new option --reset-on-fork, so we have a full
 support for the SCHED_RESET_ON_FORK flag now.

         $ chrt --fifo --reset-on-fork 1 /bin/bash
             
         $ schedutils/chrt --pid $$
         pid 31579's current scheduling policy: SCHED_FIFO|SCHED_RESET_ON_FORK
         pid 31579's current scheduling priority: 1
