Nice piece of diggin through code! A few minor nitpicks on the patch: - sob-line is missing (see Documentation/SubmittingPatches) - are there any other people who have tested this patch? If so, please include them in the patch with a Tested-by: Name Rodrigo, can you please check this patch with the docs and maybe quickly run it?
