| 5 | * Priority of a process goes from 0..MAX_PRIO-1, valid RT |
| 6 | * priority is 0..MAX_RT_PRIO-1, and SCHED_NORMAL/SCHED_BATCH |
| 7 | * tasks are in the range MAX_RT_PRIO..MAX_PRIO-1. Priority |
| 8 | * values are inverted: lower p->prio value means higher priority. |
| 9 | * |
| 10 | * The MAX_USER_RT_PRIO value allows the actual maximum |
| 11 | * RT priority to be separate from the value exported to |
| 12 | * user-space. This allows kernel threads to set their |
| 13 | * priority to a value higher than any user task. Note: |
| 14 | * MAX_RT_PRIO must not be smaller than MAX_USER_RT_PRIO. |
