Removing sysfs registration is just pointless. If you really want to save ~8k of RAM, at most you can try to move the init of the khugepaged slots hash and the kmem_cache_init to the khugepaged deamon start but even that isn't so useful. Not registering into sysfs is just pointless and it's a gratuitous loss of a feature. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
