Some boards pass. But for posteriority, looks like 2 failing cases:

Aha, are we missing the dmabuf import/export stuff on kernel 3.10 ?

If we already have an fd we shouldn't return the fd as an error and
make user space think that something is wrong.

should be fixed now

Indeed, 8060.0.0 shows all green (some platforms were not tested, though, so not marking as Verified yet).
Thank you very much for fixing my bug, Stéphane!

Only 1 platform remains untested - enguarde.
The last time gbmtest ran on it was March 12th.

Bulk verified
