From: Rob Clark <redacted> Needed in the following patch for cache operations.
Well have you seen that those callbacks are deprecated?
* Deprecated hook in favour of &drm_gem_object_funcs.pin.
* Deprecated hook in favour of &drm_gem_object_funcs.unpin.
I would rather say if you want to extend something it would be better to switch over to the per GEM object functions first. Regards, Christian.
