From 8b03ae3cde59af9facab7c831b4141515d5dbcc8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 29 Jun 2010 10:07:12 +0200 Subject: [PATCH] workqueue: introduce global cwq and unify cwq locks There is one gcwq (global cwq) per each cpu and all cwqs on an cpu point to it. A gcwq contains a lock to be used by all cwqs on the cpu and an ida to give IDs to workers belonging to the cpu. This patch introduces gcwq, moves worker_ida into gcwq and make all cwqs on the same cpu use the cpu's gcwq->lock instead of separate locks. gcwq->ida is now protected by gcwq->lock too.
