[merged mm-stable] mm-rename-vma_flag_test-set_atomic-to-vma_test-set_atomic_flag.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: rename vma_flag_test/set_atomic() to vma_test/set_atomic_flag()
has been removed from the -mm tree.  Its filename was
     mm-rename-vma_flag_test-set_atomic-to-vma_test-set_atomic_flag.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: rename vma_flag_test/set_atomic() to vma_test/set_atomic_flag()
Date: Thu, 22 Jan 2026 16:06:11 +0000

In order to stay consistent between functions which manipulate a
vm_flags_t argument of the form of vma_flags_...() and those which
manipulate a VMA (in this case the flags field of a VMA), rename
vma_flag_[test/set]_atomic() to vma_[test/set]_atomic_flag().

This lays the groundwork for adding VMA flag manipulation functions in a
subsequent commit.
