Just to be clear _these_ patches do not change the existing ABI. They do add a new ABI: the end_phys_index file. But, it is completely redundant at the moment. It could be taken out of these patches. That said, fixing the directory creation speed is probably a worthwhile endeavor too. -- Dave -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
