Its filename is mm-use-vma_lookup-instead-of-find_vma.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-use-vma_lookup-instead-of-find_vma.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: Deming Wang Subject: mm/mincore.c: use vma_lookup() instead of find_vma() Date: Thu, 6 Oct 2022 23:03:45 -0400 Using vma_lookup() verifies the start address is contained in the found vma. This results in easier to read the code.
