__start_timer
__queue_delayed_work
worker_enter_idle	worker_enter_idle - enter idle state@worker: worker which is entering idle state@worker is entering idle state. Update stats and idle timer if* necessary.* LOCKING:* spin_lock_irq(pool->lock).
rcu_torture_reader	RCU torture reader kthread. Repeatedly dereferences rcu_torture_current,* incrementing the corresponding element of the pipeline array. The* counter in the element should never be greater than 1, otherwise, the* RCU implementation is broken.
detach_if_pending
__mod_timer
add_timer	add_timer - start a timer@timer: the timer to be added The kernel will do a ->function(@timer) callback from the* timer interrupt at the ->expires point in the future
add_timer_on	add_timer_on - start a timer on a particular CPU@timer: the timer to be added@cpu: the CPU to start it on* This is not very scalable on SMP. Double adds are not possible.
del_timer	del_timer - deactivate a timer.@timer: the timer to be deactivated del_timer() deactivates a timer - this works on both active and inactive* timers.* The function returns whether it has deactivated a pending timer or not.* (ie
blk_add_timer	lk_add_timer - Start timeout timer for a single request@req: request that is about to start running. Notes:* Each request has its own timer, and as it is added to the queue, we* set up the timer. When the request completes, we cancel the timer.
blkcg_iolatency_throttle
blk_stat_is_active	lk_stat_is_active() - Check if a block statistics callback is currently* gathering statistics.*@cb: The callback.
