Subject: [merged mm-stable] mm-rmap-rename-anon_vma_interval_tree_-to-anon_rmap_tree_.patch removed from -mm tree
Date: Tue, 04 Aug 2026 19:26:01 -0700 [thread overview]
Message-ID: <20260805022602.6B2561F000E9@smtp.kernel.org> (raw)
The quilt patch titled
Subject: mm/rmap: rename anon_vma_interval_tree_*() to anon_rmap_tree_*()
has been removed from the -mm tree. Its filename was
mm-rmap-rename-anon_vma_interval_tree_-to-anon_rmap_tree_.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_*() to anon_rmap_tree_*()
Date: Fri, 10 Jul 2026 21:16:52 +0100
To be consistent with the newly renamed mapping_rmap_tree_*(), rename the
anon_vma_interval_tree_*() helpers to anon_rmap_tree_*().
No functional change intended.
