Hi. For cloned image, it is stateless about the object. when the write offset is smaller than the parent_ovelap,it need to call rbd_img_obj_exists_submit to check the object status every time. I want to save the status of the object which it is within the scope of parent_overlap. The rbd client io unit is object, so i design that use idr to save the status. The id of object is equal to write_offset >> obj_order. In the idr, said object already exists. And the idr can provide a quick query. In this way, don't need the server do anything, but need query again when remap. Looking forward to your opinion.
