From 3b07e9ca26866697616097044f25fbe53dbab693 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Mon, 20 Aug 2012 14:51:24 -0700 Subject: workqueue: deprecate system_nrt[_freezable]_wq system_nrt[_freezable]_wq are now spurious. Mark them deprecated and convert all users to system[_freezable]_wq. If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant, so there's no reason to use system_nrt[_freezable]_wq. Please use system[_freezable]_wq instead. This patch doesn't make any functional difference. Signed-off-by: Tejun Heo Acked-By: Lai Jiangshan Cc: Jens Axboe Cc: David Airlie Cc: Jiri Kosina Cc: "David S.
