Delaying, scheduling, and timer routines

struct task_cputime - collected CPU time counts
struct thread_group_cputimer - thread group interval timer counts
pid_alive - check that a task structure is not stale
is_global_init - check if a task structure is init
wake_up_process - Wake up a specific process
preempt_notifier_register - tell me when current is being preempted & rescheduled
preempt_notifier_unregister - no longer interested in preemption notifications
__wake_up - wake up threads blocked on a waitqueue.
__wake_up_sync_key - wake up threads blocked on a waitqueue.
complete - signals a single thread waiting on this completion
complete_all - signals all threads waiting on this completion
wait_for_completion - waits for completion of a task
wait_for_completion_timeout - waits for completion of a task (w/timeout)
wait_for_completion_interruptible - waits for completion of a task (w/intr)
wait_for_completion_interruptible_timeout - waits for completion (w/(to,intr))
wait_for_completion_killable - waits for completion of a task (killable)
wait_for_completion_killable_timeout - waits for completion of a task (w/(to,killable))
try_wait_for_completion - try to decrement a completion without blocking
completion_done - Test to see if a completion has any waiters
task_nice - return the nice value of a given task.
sched_setscheduler - change the scheduling policy and/or RT priority of a thread.
yield - yield the current processor to other threads.
yield_to - yield the current processor to another thread in your thread group, or accelerate that thread toward the processor it's on.
DECLARE_COMPLETION - declare and initialize a completion structure
DECLARE_COMPLETION_ONSTACK - declare and initialize a completion structure
init_completion - Initialize a dynamically allocated completion

add_timer - start a timer
add_timer_on - start a timer on a particular CPU
del_timer - deactive a timer.
try_to_del_timer_sync - Try to deactivate a timer
del_timer_sync - deactivate a timer and wait for the handler to finish.
schedule_timeout - sleep until timeout
msleep - sleep safely even with waitqueue interruptions
msleep_interruptible - sleep waiting for signals
usleep_range - Drop in replacement for udelay where wakeup is flexible
