Date: Fri, 19 Sep 2008 21:07:33 -0700 From: Arjan van de Ven <arjan@...radead.org> To: akpm@...ux-foundation.org Cc: linux-kernel@...r.kernel.org, greg@...ah.com Subject: [PATCH] debug: Introduce a dev_WARN() function From: Arjan van de Ven <arjan@...ux.intel.com> Date: Fri, 19 Sep 2008 21:03:06 -0700 Subject: [PATCH] debug: Introduce a dev_WARN() function in the line of dev_printk(), this patch introduces a dev_WARN() macro, that takes a struct device and then a printk format/args set of arguments. Unlike dev_printk(), the effect is that of WARN() in that a full warning message (including filename/line, module list, versions and a backtrace) is printed in addition to the device name and the arguments.
