From 7cda9aae0596d871a8d7a6888d7b447c60e5ab30 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Tue, 20 May 2014 17:46:32 +0800 Subject: [PATCH] workqueue: convert worker_idr to worker_ida We no longer iterate workers via worker_idr and worker_idr is used only for allocating/freeing ID, so we can convert it to worker_ida. By using ida_simple_get/remove(), worker_ida doesn't require external synchronization, so we don't need manager_mutex to protect it and the ID-removal code is allowed to be moved out from worker_detach_from_pool(). In a later patch, worker_detach_from_pool() will be used in rescuers which don't have IDs, so we move the ID-removal code out from worker_detach_from_pool() into worker_thread(). tj: Minor description updates.
