@ -78,13 +78,13 @@ Specifies deadline parameter for *SCHED_DEADLINE* policy (Linux-specific).
*-R*, *--reset-on-fork*::
Use *SCHED_RESET_ON_FORK* or *SCHED_FLAG_RESET_ON_FORK* flag. Linux-specific, supported since 2.6.31.
+
Each thread has a _reset-on-fork_ scheduling flag. When this flag is set, children created by *fork*(2) do not inherit privileged scheduling policies. After the _reset-on-fork_ flag has been enabled, it can be reset only if the thread has the *CAP_SYS_NICE* capability. This flag is disabled in child processes created by *fork*(2).
+
More precisely, if the _reset-on-fork_ flag is set, the following rules apply for subsequently created children:
+
* If the calling thread has a scheduling policy of *SCHED_FIFO* or *SCHED_RR*, the policy is reset to *SCHED_OTHER* in child processes.
+
* If the calling process has a negative nice value, the nice value is reset to zero in child processes.

This, for example, sets real-time scheduling to priority _30_ for the
process _PID_ with the *SCHED_RR* (round-robin) class:
*chrt -r -p 30 _PID_*
Reset priorities to default for a process:
*chrt -o -p 0 _PID_*

classes and how they interact.
