Hi, Christoph,Thanks for your reply!

Currently, the number of block devices will depend on both the number of
namespaces configured in a subsystem and the number of connections created by
connect command.

In addition , I still have the suggestion:
Can this feature or problematic behavior be adjusted to prevent generating
another block devices when a new connection is created from a given host to
a subsystem via the same patho< Maybe a character device (controller) or
block device (namespaces) can represent more connections given the same path.

Looking forward for you response. Thanks.
