cancel_delayed_work — cancel a delayed work
bool cancel_delayed_work ( | struct delayed_work * dwork); |
Kill off a pending delayed_work. Returns true if dwork was pending
and canceled; false if wasn't pending. Note that the work callback
function may still be running on return, unless it returns true and the
work doesn't re-arm itself. Explicitly flush or use
cancel_delayed_work_sync to wait on it.
This function is safe to call from any context including IRQ handler.
