Subject: [PATCH v7 04/14] drivers: dax: use pgtable_has_pmd_leaves()
Date: Mon, 31 Aug 2026 23:12:08 -0400	[thread overview]
Message-ID: <bfa653ca6aae4765a026437c5bb231ff839c0586.1788232334.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1788232334.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>
