Its filename is mm-vmalloc-remove-global-vmap_area_root-rb-tree-fix.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-vmalloc-remove-global-vmap_area_root-rb-tree-fix.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: "Uladzislau Rezki (Sony)" Subject: mm: vmalloc: mark vmap_init_free_space() with __init tag Date: Thu, 11 Jan 2024 14:26:28 +0100 vmap_init_free_space() is called only once therefore tag it with __init. Apart of that it access the "vmlist" variable that is located in ".init.data" section.
