From bf6aede712334d7338d5c47a5ee5ba3883c82a61 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 2 Apr 2009 16:56:54 -0700 Subject: workqueue: add to_delayed_work() helper function It is a fairly common operation to have a pointer to a work and to need a pointer to the delayed work it is contained in. In particular, all delayed works which want to rearm themselves will have to do that. So it would seem fair to offer a helper function for this operation.
