Subject: [RFC 06/10] mm: debug_vm_pgtable: use pgtable_has_pmd_leaves()
Date: Thu, 6 Nov 2025 16:28:53 -0500 [thread overview]
Message-ID: <237bcb7f3d832457322210cc7f8d1272c4ac88ef.1762464515.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1762464515.git.luizcap@redhat.com>
debug_vm_pgtable calls has_transparent_hugepage() in multiple places to
check if PMD-sized pages are supported, use pgtable_has_pmd_leaves()
instead.
