Previously, both map and remap trigger rnbd_clt_set_dev_attr to set some members in rnbd_clt_dev such as wc, fua and logical_block_size etc, but those members are only useful for map scenario given the setup_request_queue is only called from the path: rnbd_clt_map_device -> rnbd_client_setup_device Since rnbd_clt_map_device frees rsp after rnbd_client_setup_device, we can pass rsp to rnbd_client_setup_device and it's callees, which means queue's attributes can be set directly from relevant members of rsp instead from rnbd_clt_dev. After that, we can kill 11 members from rnbd_clt_dev, and we don't need rnbd_clt_set_dev_attr either.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
