From f425821b946847282708121600fffc20344183a0 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Thu, 10 Jun 2021 09:01:51 +0200 Subject: [PATCH] drm/vma: Add a driver_private member to vma_node. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows drivers to distinguish between different types of vma_node's. The readonly flag was unused and is thus removed. This is a temporary solution, until i915 is converted completely to use ttm for bo's.
