From e5cba24e3f018d4beb6acd101a82483c98f91ce7 Mon Sep 17 00:00:00 2001 From: Hitoshi Mitake Date: Fri, 26 Nov 2010 12:06:44 +0100 Subject: [PATCH] workqueue: check the allocation of system_unbound_wq I found a trivial bug on initialization of workqueue. Current init_workqueues doesn't check the result of allocation of system_unbound_wq, this should be checked like other queues.
