Subject: [PATCH v2 02/14] mm/page_alloc: add helper for checking if check_pages_enabled
Date: Tue, 21 Mar 2023 19:05:01 +0200 [thread overview]
Message-ID: <20230321170513.2401534-3-rppt@kernel.org> (raw)
In-Reply-To: <20230321170513.2401534-1-rppt@kernel.org>
From: "Mike Rapoport (IBM)" <rppt@kernel.org>
Instead of duplicating long static_branch_enabled(&check_pages_enabled)
wrap it in a helper function is_check_pages_enabled()
Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org>
