Subject: [PATCH v10 10/11] drm/vma: Add a driver_private member to vma_node.
Date: Wed,  2 Jun 2021 10:38:17 +0200	[thread overview]
Message-ID: <20210602083818.241793-11-thomas.hellstrom@linux.intel.com> (raw)
In-Reply-To: <20210602083818.241793-1-thomas.hellstrom@linux.intel.com>

From: Maarten Lankhorst <maarten.lankhorst@linux.intel.com>

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.
