Re: [PATCH 3/6] workqueue: make cancel_rearming_delayed_workqueue() work on idle dwork

cancel_rearming_delayed_workqueue(dwork) will hang forever if dwork was not

Thanks! We hit this problem before with the zd1211rw driver and avoidedusing cancel_rearming_delayed_workqueue() for this reason. I never didget around to looking into if the function itself could be fixed,although I see not much effort would have been needed :)
