In ext4 we have many different debugging patches, and in general you'd never want to enable them all at once (you'd get way too much noise). The debugging statements are there when a developer is debugging very specific section of code (i.e., the directory index, or the extent tree, or the block allocator, etc.). It's really only ext4 developers who need to use those debugging statements, and even for them it's quite rare. So I've never considered it worthwhile to enable them via a CONFIG_* menu item; developers who are debugging a specific problem will generally just drop in the specific #define on an ad hoc basis, and that works fine. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
