[merged mm-stable] mm-rmap-rename-anon_vma_interval_tree_-params-and-use-pgoff_t.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/rmap: rename anon_vma_interval_tree_*() params and use pgoff_t
has been removed from the -mm tree.  Its filename was
     mm-rmap-rename-anon_vma_interval_tree_-params-and-use-pgoff_t.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

------------------------------------------------------
From: Lorenzo Stoakes <ljs@kernel.org>
Subject: mm/rmap: rename anon_vma_interval_tree_*() params and use pgoff_t
Date: Fri, 10 Jul 2026 21:16:51 +0100

Rename parameters used by anon_vma_interval_tree_*() functions: 'node' to
'avc', 'start/first' to 'pgoff_start', and 'last' to 'pgoff_last' to make
clear what is being passed.

Also, express page offsets in terms of pgoff_t to be consistent.

No functional change intended.
