Subject: [PATCH v3 03/10] drivers: dax: use pgtable_has_pmd_leaves()
Date: Wed, 8 Apr 2026 16:22:58 -0400 [thread overview]
Message-ID: <a62158b3c271b02c7a6d5502b14b2f9972b8615a.1775679721.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1775679721.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>
