I updated my patches which remove zone and node ID from page->flags. Page->flags is 32bit space and 19 bits of them have already been used on 2.6.9-rc2-mm2 kernel, and zone and node ID uses 8 bits on 32 archtecture. So, remaining bits is only 5 bits. In addition, only 3 bits have remained on 2.6.8.1 stock kernel. But, my patches make more 8 bits space in page->flags again. And kernel can use large number of node and types of zone. These patches are for 2.6.9-rc2-mm2. Please comment. Bye. -- Yasunori Goto -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
