Remove all block device related info from ublksrv_ctrl_dev_info, meantime reduce its size into 64 bytes because: 1) ublksrv_ctrl_dev_info becomes cleaner without including any block related info 2) generic set/get parameter command can be used to set block related setting easily and cleanly 3) generic set/get parameter command can be used for extending ublk without needing more info in ublksrv_ctrl_dev_info Signed-off-by: Ming Lei <ming.lei@redhat.com> Link: https://lore.kernel.org/r/20220730092750.1118167-5-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
