The six callers of nvmet_find_namespace() duplicate the error log page update and status setting code for each call on failure. All callers are nvmet requests based functions, so we can pass req to the nvmet_find_namesapce() & derive ctrl from req, that'll allow us to update the error log page in nvmet_find_namespace(). Now that we pass the request we can also get rid of the local variable in nvmet_find_namespace() and use the req->ns and return the error code. Replace the ctrl parameter with nvmet_req for nvmet_find_namespace(), centralize the error log page update for non allocated namesapces, and return uniform error for non-allocated namespace. The nvmet_find_namespace() takes nsid parameter which is from NVMe commands structures such as get_log_page, identify, rw and common. All these commands have same offset for the nsid field. Derive nsid from req->cmd->common.nsid) & remove the extra parameter from the nvmet_find_namespace(). Lastly now we associate the ns to the req parameter that we pass to the nvmet_find_namespace(), rename nvmet_find_namespace() to nvmet_req_find_ns().

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.
