The quilt patch titled
     Subject: mm/ksm: convert VMA flag tests to use vma_flags_t

------------------------------------------------------
From: "Lorenzo Stoakes (ARM)" <ljs@kernel.org>
Subject: mm/ksm: convert VMA flag tests to use vma_flags_t
Date: Thu, 05 Nov 2026 21:30:57 +0000

Replace use of the legacy vm_flags_t flags with vma_flags_t values where
KSM tests VMA flags directly.

The ksm_madvise() interface continues to take legacy flags for the time
being.

No functional change intended.
