Subject: mm: hugeltb: check NUMA_NO_NODE in only_alloc_fresh_hugetlb_folio()
Date: Tue, 2 Sep 2025 20:48:16 +0800

Move the NUMA_NO_NODE check out of buddy and gigantic folio allocation to
cleanup code a bit, also this will avoid NUMA_NO_NODE passed as 'nid' to
node_isset() in alloc_buddy_hugetlb_folio().
