I would prefer if you would remove this strange feature from slob. The ksize for a !PageSlab() "slab" page is always PAGE_SIZE << compound_order(page). There is no need to use page->private here. It is a bad practice to not mark a page as a slab page but then use fields for special purposes. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
