Were you using the older /dev/rbd style setup on purpose? If so why? Was it for performance reasons?

You mean why don't I use the tcmu-runner? Some time ago I was also verifying the use of tcmu-runner in our products. But tcmu-runner requires kernel version 7.5,Our products cannot upgrade the kernel temporarily，so we are using the older style(map the block device on the Ceph cluster to the gateway node locally,then export it to /backstores/block)

the gwtop has two choices in porvider, lio and dm. Is the older style the provider of dm?
