2691  DEFINE_MUTEX(mutex)
2693  mutex_lock( & mutex)
2694  ret等于读sysctl整数向量
2699  如果非ret且write则
2700  sched_rr_timeslice等于如果sysctl_sched_rr_timeslice小于等于0则default timeslice is 100 msecs (used only for SCHED_RR tasks).* Timeslices get refilled after they expire.否则msecs_to_jiffies: - convert milliseconds to jiffies*@m: time in milliseconds* conversion is done as follows:* - negative values mean 'infinite timeout' (MAX_JIFFY_OFFSET)* - 'too large' values [that would result in larger than
