[PATCH 1/2] 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.

[PATCH] libdrm/nouveau: safen up nouveau libdrm against concurrent access
Based on the original patch by Ilia Mirkin. Handle races between nouveau_bo_name_get, nouveau_bo_prime_handle_ref and unreffing. Because DRM_IOCTL_GEM_CLOSE is not refcounted, some special care was needed by holding the lock during some ioctls.
