NAME
       yield_to - yield the current processor to another thread in your thread group, or
       accelerate that thread toward the processor it's on.

SYNOPSIS
       int __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.
