Subject: [PATCH 5/8] drm: use drm_file to tag vm-bos
Date: Wed,  3 Aug 2016 20:04:29 +0200	[thread overview]
Message-ID: <20160803180432.1341-6-dh.herrmann@gmail.com> (raw)
In-Reply-To: <20160803180432.1341-1-dh.herrmann@gmail.com>

Rather than using "struct file*", use "struct drm_file*" as tag VM tag for
BOs. This will pave the way for "struct drm_file*" without any "struct
file*" back-pointer.
