Please take considerably more care when preparing patch changelogs. kmap_atomic() is a very commonly called function so we'll need much more detail than this to justify adding overhead to it. I don't think CONFIG_DEBUG_HIGHMEM really needs to exist. We could do s/CONFIG_DEBUG_HIGHMEM/CONFIG_DEBUG_VM/g and perhaps your secret bug whatever it was would have been found more easily. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
