3 * linux/kernel/softirq.c
11 * Remote softirq infrastructure is by Jens Axboe.
43 - If a softirq needs serialization, let it serialize itself
45 - Even if softirq is serialized, only local cpu is marked for
51 - NET RX softirq. It is multithreaded and does not require
53 - NET TX softirq. It kicks software netdevice queues, hence
77 * the softirq load for us.
89 * This one is for softirq.c-internal use,
160 * softirq processing:
187 * We restart softirq processing MAX_SOFTIRQ_RESTART times,
238 printk(KERN_ERR "huh, entered softirq %td %s %p"
338 * If we're in an interrupt or softirq, we're done
339 * (this also catches softirq-disabled code). We will
340 * actually run the softirq once we return from
341 * the irq or softirq.
344 * schedule the softirq soon.
521 * hrtimer callback, but from softirq context.
534 * tasklet/softirq context
547 * tasklet_hrtimer_init - Init a tasklet/hrtimer combo for softirq callbacks
549 * @function: hrtimer callback funtion which gets called from softirq context
566 * Remote softirq bits
