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.

In case we have already established connection to nvmf target, it shouldn't be allowed to change the model_number. E.g. if someone will identify ctrl and get model_number of "my_model" later on will change the model_numbel via configfs to "my_new_model" this will break the NVMe specification for "Get Log Page – Persistent Event Log" that refers to Model Number as: "This field contains the same value as reported in the Model Number field of the Identify Controller data structure, bytes 63:24." Although it doesn't mentioned explicitly that this field can't be changed, we can assume it. So allow setting this field only once: using configfs or in the first identify ctrl operation.
