- * gem handles.
- *
- * 2) The algorithm we use for building the list of unique buffers isn't

- * QueueSubmit, this would be extremely difficult to debug if it ever
- * came up in the wild due to a broken app. It's better to play it
- * safe and just lock around QueueSubmit.
- *
- * 3) The anv_cmd_buffer_execbuf function may perform relocations in

- * threads at the same time. Even though the user is supposed to
- * ensure this doesn't happen, we play it safe as in (2) above.

- * pool resize only rarely happen, this will almost never be contended so
