Subject: [PATCH v3 05/10] mm: debug_vm_pgtable: use pgtable_has_pmd_leaves()
Date: Wed, 8 Apr 2026 16:23:00 -0400 [thread overview]
Message-ID: <18d82575497d06a4d18605ae33f9c22e08a3209e.1775679721.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1775679721.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.
