[PATCH v5 0/6] DRM_SET_CLIENT_NAME ioctl

[Pierre-Eric Pelloux-Prayer]

v5 of this series which is adding a new ioctl to let userspace associate
a free-form name to a drm_file.

Having this name is useful when debugging or tracking resource usage; in
particular when using virtio native-context driver, where a single process
(say QEMU), uses 1 drm_file per-guest application.
With this change, fdinfo and other tools can map each drm_file activity to
the guest application.

virglrenderer MR using this new ioctl to associate the context "debug_name"
to the fd:

Changes since v4:
* patches 1, 4 and 6 were slightly reworked based on Tvrtko' suggestions.
