You are correct, PageReserved might be tested in offlined memory, if we go with the proposed solution, we might even need to add "struct page" poisoning instead of memset(0) in sparse_add_one_section when debugging is enabled. Similar to what we do during boot in memblock_virt_alloc_raw() The fix would imply to ensure that PageReserved is never tested and page_to_nid is never executed for offlined memory. I will study for possible solutions. Thank you, Pavel -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
