Proto:static void prio_changed_rt(struct rq *rq, struct task_struct *p, int oldprio)

Type:void

Parameter:

TypeParameterName
struct rq *rq
struct task_struct *p
intoldprio
2242  If Not task_on_rq_queued(p) Then Return
2245  If curr == p Then
2262  If oldprio < prio Then sched_curr - mark rq's current task 'to be rescheduled now'.* On UP this means the setting of the need_resched flag, on SMP it* might also involve a cross-CPU call to trigger the scheduler on* the target CPU.
2265  Else
2271  If prio < prio Then sched_curr - mark rq's current task 'to be rescheduled now'.* On UP this means the setting of the need_resched flag, on SMP it* might also involve a cross-CPU call to trigger the scheduler on* the target CPU.
