The patch titled Subject: mm/mm_init.c: only align start of ZONE_MOVALBE on nodes with memory has been added to the -mm mm-unstable branch. Its filename is mm-mm_initc-only-align-start-of-zone_movalbe-on-nodes-with-memory.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-mm_initc-only-align-start-of-zone_movalbe-on-nodes-with-memory.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: Wei Yang <richard.weiyang@xxxxxxxxx> Subject: mm/mm_init.c: only align start of ZONE_MOVALBE on nodes with memory Date: Tue, 11 Feb 2025 08:29:00 +0000 At the beginning of find_zone_movable_pfns_for_nodes(), it has properly set node_states[N_MEMORY] in early_calculate_totalpages(). Instead of iterating over all possible nodes, we can just do the alignment on nodes with memory.
