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, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
