...ush_work, and then splitting kthread_flush_work() into two functions: kthread_queue_flush_work(); which handles possibly queuing up the kthread_flush_work on the work's respective kthread_worker, and kthread_flush_work(); which performs a simple synchronous flush just like before. We also add a DEFINE_KTHREAD_FLUSH_WORK() macro, which simply initializes a kthread_flush_work struct inline (I can't see anyone needing to use a kthread_flush_work that gets used outside of the scope of a single function, and that seems like it would be a bit overkill anyway).

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up
