From f5a421a4509a7e2dff11da0f01b0548f4f84d503 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Sun, 15 Jul 2007 23:41:44 -0700 Subject: [PATCH] rename cancel_rearming_delayed_work() to cancel_delayed_work_sync() Imho, the current naming of cancel_xxx workqueue functions is very confusing. cancel_delayed_work() cancel_rearming_delayed_work() cancel_rearming_delayed_workqueue() // obsolete cancel_work_sync() This looks as if the first 2 functions differ in "type" of their argument which is not true any longer, nowadays the difference is the behaviour. The semantics of cancel_rearming_delayed_work(dwork) was changed significantly, it doesn't require that dwork rearms itself, and cancels dwork synchronously. Rename it to cancel_delayed_work_sync(). This matches cancel_delayed_work() and cancel_work_sync(). Re-create cancel_rearming_delayed_work() as a simple inline obsolete wrapper, like cancel_rearming_delayed_workqueue().
