The patch titled Subject: mm/mm_init.c: remove meaningless calculation of zone->managed_pages in free_area_init_core() has been added to the -mm mm-unstable branch. Its filename is mm-mm_initc-remove-meaningless-calculation-of-zone-managed_pages-in-free_area_init_core-v3.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-remove-meaningless-calculation-of-zone-managed_pages-in-free_area_init_core-v3.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: Baoquan He <bhe@xxxxxxxxxx> Subject: mm/mm_init.c: remove meaningless calculation of zone->managed_pages in free_area_init_core() Date: Thu, 28 Mar 2024 17:12:14 +0800 Change to initialize zone->managed_pages as zone->present_pages for now because later page_group_by_mobility_disabled need be set according to zone->managed_pages. Otherwise it will cause setting page_group_by_mobility_disabled to 1 always.
