YIELD_TO(9)							   Driver Basics						       YIELD_TO(9)

yield_to - yield the current processor to another thread in your thread group, or accelerate that thread toward the processor it's on. SYNOPSIS
bool __sched yield_to(struct task_struct * p, bool preempt); ARGUMENTS
p target task preempt whether task preemption is allowed or not DESCRIPTION
It's the caller's job to ensure that the target task struct can't go away on us before we can do any checks. RETURN
true (>0) if we indeed boosted the target task. false (0) if we failed to boost the target. -ESRCH if there's no task to yield to. COPYRIGHT

SCHEDULE_HRTIMEOUT_R(9) 					   Driver Basics					   SCHEDULE_HRTIMEOUT_R(9)

schedule_hrtimeout_range - sleep until timeout SYNOPSIS
int __sched schedule_hrtimeout_range(ktime_t * expires, unsigned long delta, const enum hrtimer_mode mode); ARGUMENTS
expires timeout value (ktime_t) delta slack in expires timeout (ktime_t) mode timer mode, HRTIMER_MODE_ABS or HRTIMER_MODE_REL DESCRIPTION
Make the current task sleep until the given expiry time has elapsed. The routine will return immediately unless the current task state has been set (see set_current_state). The delta argument gives the kernel the freedom to schedule the actual wakeup to a time that is both power and performance friendly. The kernel give the normal best effort behavior for "expires+delta", but may decide to fire the timer earlier, but no earlier than expires. You can set the task state as follows - TASK_UNINTERRUPTIBLE - at least timeout time is guaranteed to pass before the routine returns. TASK_INTERRUPTIBLE - the routine may return early if a signal is delivered to the current task. The current task state is guaranteed to be TASK_RUNNING when this routine returns. Returns 0 when the timer has expired otherwise -EINTR COPYRIGHT
