Simplify this code by making the memory manager call the rsp. functions of the BOs directly; and remove the functions from the BO's public interface. v2: * typos in commit message Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190911110910.30698-3-tzimmermann@suse.de
