From 43829731dd372d04d6706c51052b9dabab9ca356 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 20 Aug 2012 14:51:24 -0700 Subject: workqueue: deprecate flush[_delayed]_work_sync() flush[_delayed]_work_sync() are now spurious. Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.
