Subject: [RFC PATCH 0/2] dmabuf import interfaces for vgem

Hi,

Ion[1] is making progress towards moving out of staging. I'd like to take
advantage of the vgem driver for development of unit tests for Ion. To
do this properly, vgem needs to support importing of foreign handles. This
is an RFC to add that support. This passes the existing vgem_basic unit
test. I plan to extend that test with support for testing import as well.
RFC is for general direction and feedback since I'm not that familiar with
DRM internals.

Thanks,
Laura
