Hi,
This is v10 of the writeback connector series. Compared to v9 I've reverted to the v6 way of cleaning up the writeback job in the cleanup_work() function, where we also drop the reference to the job's framebuffer. I was trying to come up with a reference counted implementation for the job, but Sean Paul pointed out to Brian that it seems to be safe to free work_struct structures in the workqueue callback, so we are going back to the original implementation.
While doing that, I've also updated the patcheset to use the latest drm_framebuffer_{put,get,assign} functions for managing the framebuffer reference that the wriback job holds.
I will ask Gustavo to pull this series into drm-misc if there are no further comments.
Best regards, Liviu
