This should to be also mentioned the changelog of each patch. There are 12 subsystems changed, this could be about 10 maintainers and I guess everybody has the same question why the change is made. The conversion is not exactly the same in all patches, the simple pointer -> static variable can be possibly covered by the same generic text but as Mike points out the alignment changes should be at least mentioned for consideration otherwise. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
