From 6a898c2757af1ac852bb917a0866d2724f303076 Mon Sep 17 00:00:00 2001 From: Yuan Can Date: Wed, 6 Sep 2023 17:31:57 +0800 Subject: [PATCH] mm: hugetlb_vmemmap: allow alloc vmemmap pages fallback to other nodes In vmemmap_remap_free(), a new head vmemmap page is allocated to avoid breaking a contiguous block of struct page memory, however, the allocation can always fail when the given node is movable node. Remove the __GFP_THISNODE to help avoid fragmentation.
