From 55f67f2dedec1e3049abc30b6d82b999a14cafb7 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Tue, 16 Feb 2010 18:42:51 +0000 Subject: [PATCH] dm snapshot: persistent annotate work_queue as on stack chunk_io() declares its 'struct mdata_req' on the stack and then initializes its 'struct work_struct' member. Annotate the initialization of this workqueue with INIT_WORK_ON_STACK to suppress a debugobjects warning seen when CONFIG_DEBUG_OBJECTS_WORK is enabled.
