[PATCH 1/1] drm/qxl: add mutex_lock/mutex_unlock to ensure the order in which resources are released.

So the dma_resv_reserve_shared() call in qxl_release_validate_bo() is
unbalanced? Because the dma_resv_unlock() call in
qxl_release_fence_buffer_objects() never happens due to
qxl_release_free_list() clearing the list beforehand? Is that correct?
The only way I see for this to happen is that the guest is preempted
between qxl...

[PATCH 0/6] drm/nouveau: Support sync FDs and sync objects
From: Thierry Reding <treding at nvidia.com>
Hi,
This series implements a new IOCTL to submit push buffers that can
optionally return a sync FD or sync object to userspace. This is useful
in cases where userspace wants to synchronize operations between the GPU
and another driver (such as KMS for display). Among other things this
allows extensions such as eglDupNativeFenceFDANDROID to be
