* sched: rt: document the risk of small values in the bandwidth settingsPeter Zijlstra2009-05-051-0/+18
| | | | | | | | | | | | | | Thomas noted that we should disallow sysctl_sched_rt_runtime == 0 for (!RT_GROUP) since the root group always has some RT tasks in it. Further, update the documentation to inspire clue.
