Assuming we have 2 NUMA Node,\nwhen traversing Node1 in ac->zonelist, the nodemask is 2, and when\ntraversing Node2 in ac->zonelist, the nodemask is 1.  As a result, the\nac->preferred_zoneref points to NULL zone.\n\nIn alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a\nallowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading\nto NULL pointer dereference.\n\n__alloc_pages_noprof() fixes this issue by checking NULL pointer in commit\nea57485af8f4 (\"mm, page_alloc: fix check for NULL preferred_zone\") and\ncommit df76cee6bbeb (\"mm, page_alloc: remove redundant checks from alloc\nfastpath\").\n\nTo fix it, check NULL pointer for preferred_zoneref->zone."
