comments:
- This have been discussed in the past, see wiki/Chat_log/20180405-mm-chatlog.
- The conclusion in 2018 was there are not many use-cases for this that are
not better served by DMABUF. We would like to know more about this use-case
before upporting this if possible.
- USERPTR is considered deprecated upstream, marking as abandoned.
