> [PATCH] nice and rt-prio rlimits
>
> Add a pair of rlimits for allowing non-root tasks to raise nice and rt
> priorities. Defaults to traditional behavior. Originally written by
> Chris Wright.
>
> The patch implements a simple rlimit ceiling for the RT (and nice)
> priorities
> a task can set. The rlimit defaults to 0, meaning no change in behavior by
> default. A value of 50 means RT priority levels 1-50 are allowed. A
> value of
> 100 means all 99 privilege levels from 1 to 99 are allowed. CAP_SYS_NICE is
> blanket permission.
