Subject: + tools-testing-vma-use-vma_start_pgoff-in-merge-tests.patch added to mm-new branch
Date: Fri, 10 Jul 2026 15:45:42 -0700 [thread overview]
Message-ID: <20260710224543.48E2D1F000E9@smtp.kernel.org> (raw)
The patch titled
Subject: tools/testing/vma: use vma_start_pgoff() in merge tests
has been added to the -mm mm-new branch. Its filename is
tools-testing-vma-use-vma_start_pgoff-in-merge-tests.patch
This patch will shortly appear at
https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/tools-testing-vma-use-vma_start_pgoff-in-merge-tests.patch
This patch will later appear in the mm-new branch at
git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews. Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.
The mm-new branch of mm.git is not included in linux-next
If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next
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 various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
and is updated there most days

Subject: tools/testing/vma: use vma_start_pgoff() in merge tests
Date: Fri, 10 Jul 2026 21:16:44 +0100
Now we have the vma_start_pgoff() helper, update the merge tests to make
use of it for consistency.
No functional change intended.
