Subject: [PATCH v4 3/9] drivers: dax: use pgtable_has_pmd_leaves()
Date: Fri, 1 May 2026 15:18:45 -0400 [thread overview]
Message-ID: <cb854ba26a4b8036706c6da5f6844f10f386087f.1777663129.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1777663129.git.luizcap@redhat.com>
dax_align_valid() uses has_transparent_hugepage() to check if PMD-sized
pages are supported, use pgtable_has_pmd_leaves() instead.
Acked-by: David Hildenbrand (Red Hat) <david@kernel.org>
