If this does need to be configured per system would having platform data of some kind in the kernel not be a sensible a place to do it, or even having a way of configuring this at runtime (after all, the set of currently active users may vary depending on the current configuration and keeping everything allocated all the time may be wasteful)? -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
