[merged mm-stable] mm-add-vma_desc_test_all-and-use-it.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: mm: add vma_desc_test_all() and use it
has been removed from the -mm tree.  Its filename was
     mm-add-vma_desc_test_all-and-use-it.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: add vma_desc_test_all() and use it
Date: Thu, 5 Mar 2026 10:50:15 +0000

erofs and zonefs are using vma_desc_test_any() twice to check whether all
of VMA_SHARED_BIT and VMA_MAYWRITE_BIT are set, this is silly, so add
vma_desc_test_all() to test all flags and update erofs and zonefs to use
it.

While we're here, update the helper function comments to be more
consistent.

Also add the same to the VMA test headers.
