# cancel\_work\_sync(9)

cancel a work and wait for it to finish

## NAME

cancel\_work\_sync - cancel a work and wait for it to finish

## SYNOPSIS

**bool cancel\_work\_sync(struct work\_struct \*** *work***);**

## ARGUMENTS

*work*

the work to cancel

## DESCRIPTION

Cancel *work* and wait for its execution to finish. This function can be used even if the work re-queues itself or migrates to another workqueue. On return from this function, *work* is guaranteed to be not pending or executing on any CPU.

cancel\_work\_sync(delayed\_work-\>work) must not be used for delayed\_work's. Use **cancel\_delayed\_work\_sync** instead.

The caller must ensure that the workqueue on which *work* was last queued can't be destroyed before this function returns.

## RETURN

**true** if *work* was pending, **false** otherwise.
