* Name: work_cancel

|

* Description:
|
|
* Cancel previously queued work. This removes work from the work queue.
|
|
* After work has been canceled, it may be re-queue by calling work_queue()
|
|
* again.
|
|
*
|
|
* Input parameters:
|
|
* qid - The work queue ID
|
|
* work - The previously queue work structure to cancel
|
|
*
|
|
* Returned Value:
|
|
* Zero on success, a negated errno on failure
|
|
