This series contains the drm and i915 bits required to implement the VK_KHR_external_semaphore and VK_KHR_external_fence extensions on top of DRM sync objects. Patches 1-3 are cleanups and fixes for the core syncobj APIs. Patch 4 is the i915 patch that adds support for syncobj in the i915 driver. I'm re-sending it because I've rebased the latest version on patches 1-3. Patch 6 is technically not required by the end of the series but is needed for i915 if we don't have patches 7-9. I think it's a good and possibly useful clean-up, but I'm more than willing to drop it in favor of 7-9. Patch 7 adds a reset ioctl which allows the caller to reset the syncobj by setting the fence to NULL. This is needed to implement vkResetFences. The real meat of the series is patches 8 and 9. The previous wait implementation would throw -EINVAL if you ever tried to wait on a syncobj which did not yet have a dma_fence. Patch 9 adds a new flag to the syncobj which makes it so that, if it does not yet have a fence, it first waits for a fence to show up and then waits on the fence. This is needed to properly implement VkWaitForFences behavior.
