NAME
       workqueue_congested - test whether a workqueue is congested

SYNOPSIS
       bool workqueue_congested(int cpu, struct workqueue_struct * wq);

ARGUMENTS
       cpu
	   CPU in question

       wq
	   target workqueue

DESCRIPTION
       Test whether wq's cpu workqueue for cpu is congested. There is no
       synchronization around this function and the test result is unreliable
       and only useful as advisory hints or for debugging.

       If cpu is WORK_CPU_UNBOUND, the test is performed on the local CPU.
       Note that both per-cpu and unbound workqueues may be associated with
       multiple pool_workqueues which have separate congested states. A
       workqueue being congested on one CPU doesn't mean the workqueue is also
       contested on other CPUs / NUMA nodes.

RETURNS
       true if congested, false otherwise.
