Message-Id: <1357687455-13234-1-git-send-email-cody@linux.vnet.ibm.com> Date: Tue, 8 Jan 2013 15:24:13 -0800 From: Cody P Schafer <cody@...ux.vnet.ibm.com> To: LKML <linux-kernel@...r.kernel.org> Cc: Mel Gorman <mgorman@...e.de>, Andrew Morton <akpm@...ux-foundation.org> Subject: [PATCH 0/2] Add decoder for GFP masks to tools. I needed to decode some gfp_masks to debug an oom-killer invocation, and wrote this tool to avoid doing the decoding manually. Bad things about this: slightly hacky use of code intended for use with ftrace, splitting linux/gfp.h into 2 parts. Good things: No additional places need modification to keep the decoder up to date, no mistakes from manual gfp_mask decoding. include/linux/gfp-flags.h | 143 +++++++++++++++++++++++++++++++++++++++++ include/linux/gfp.h | 144 +----------------------------------------- tools/gfp-decode/.gitignore | 1 + tools/gfp-decode/Makefile | 11 ++++ tools/gfp-decode/gfp-decode.c | 89 ++++++++++++++++++++++++++ 5 files changed, 245 insertions(+), 143 deletions(-) --- On the topic of writing Makefiles for tools/*, it would be extremely convienient if a system was setup which allowed simple specification of final executable(s) and the objects to compose them rather than having each tool write a custom Makefile. For example (potentially): TARGETS = gfp-decode obj-gfp-decode = gfp-decode.o include ../scripts/Makefile.magic -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
