From 440a11360326044a9addf1c652a0364aad0be90c Mon Sep 17 00:00:00 2001 From: Chuansheng Liu Date: Sat, 11 Jan 2014 22:26:33 -0500 Subject: [PATCH] workqueue: Calling destroy_work_on_stack() to pair with INIT_WORK_ONSTACK() In case CONFIG_DEBUG_OBJECTS_WORK is defined, it is needed to call destroy_work_on_stack() which frees the debug object to pair with INIT_WORK_ONSTACK().
