int | nice |
210 | next = Have the 32 bit jiffies value wrap 5 minutes after boot* so jiffies wrap bugs show up earlier. |

222 | If nice < 0 && Not an_nice - check if a task can reduce its nice value*@p: task*@nice: nice value Then Return -EPERM |
226 | If Not Check operation authority && time_before(jiffies, next) Then Return -EAGAIN |
