Subject: [PATCH 06/11] mm: debug_vm_pgtable: use pgtable_has_pmd_leaves()
Date: Mon, 15 Dec 2025 16:16:48 -0500 [thread overview]
Message-ID: <6a4f0f6faf164aa3578d1c215fcd964fcd2f0659.1765833318.git.luizcap@redhat.com> (raw)
In-Reply-To: <cover.1765833318.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.
