Subject: [RFC 03/10] drivers: dax: use pgtable_has_pmd_leaves()
Date: Thu, 6 Nov 2025 16:28:50 -0500 [thread overview]
Message-ID: <1456ba4c025e9ea01abcadb8c3714c7ef84e0198.1762464515.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1762464515.git.luizcap@redhat.com>
dav_align_valid() uses has_transparent_hugepage() to check if PMD-sized
pages are supported, use pgtable_has_pmd_leaves() instead.
