Message-ID: <1421942223.68903704@f406.i.mail.ru> (raw)
I continue to study the task scheduler O(1)?
I do not understand what makes this part of the code ?
1317 void kick_process(struct task_struct *p)
1318 {
1319???????? int cpu;
1320
1321???????? preempt_disable();
1322???????? cpu = task_cpu(p);
1323???????? if ((cpu != smp_processor_id()) && task_curr(p))
1324???????????????? smp_send_reschedule(cpu);
1325???????? preempt_enable();
link to source code : http://lxr.free-electrons.com/source/kernel/sched/core.c#L1317
what it means to do this function kick_process ?
I just met her for the first time
?
If you say I will be very grateful to you for your help
