nouveau: make nouveau importing global buffers completely thread-safe, with tests
While I've closed off most races in a previous patch, a small race still existed where importing then unreffing cound cause an invalid bo. Add a test for this case. Racing sequence fixed: - thread 1 releases bo, refcount drops to zero, blocks on acquiring nvdev->lock. - thread 2 increases refcount to 1. - thread 2 decreases refcount to zero, blocks on acquiring nvdev->lock. At this point the 2 threads will clean up the same bo. Signed-off-by: Maarten Lankhorst <maarten.lankhorst@ubuntu.com> Reviewed-By: Emil Velikov <emil.l.velikov@gmail.com>
