Its filename is mm-hugetlb_vmemmap-allow-alloc-vmemmap-pages-fallback-to-other-nodes.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-hugetlb_vmemmap-allow-alloc-vmemmap-pages-fallback-to-other-nodes.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Yuan Can Subject: mm: hugetlb_vmemmap: allow alloc vmemmap pages fallback to other nodes Date: Wed, 6 Sep 2023 17:31:57 +0800 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.
