[merged mm-stable] mm-memory-inline-unmap_mapping_range_vma-into-unmap_mapping_range_tree.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm/memory: inline unmap_mapping_range_vma() into unmap_mapping_range_tree()
has been removed from the -mm tree.  Its filename was
     mm-memory-inline-unmap_mapping_range_vma-into-unmap_mapping_range_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

Subject: mm/memory: inline unmap_mapping_range_vma() into unmap_mapping_range_tree()
Date: Fri, 27 Feb 2026 21:08:34 +0100

Let's remove the number of unmap-related functions that cause confusion by
inlining unmap_mapping_range_vma() into its single caller.  The end result
looks pretty readable.
