[ Upstream commit e3ba04c9bad1d1c7f15df43da25e878045150777 ] There are reports of multiple ports on the same system displaying different hostnames in fabric FDMI displays. Currently, the driver registers the hostname at initialization and obtains the hostname via init_utsname()->nodename queried at the time the FC link comes up. Unfortunately, if the machine hostname is updated after initialization, such as via DHCP or admin command, the value registered initially will be incorrect. Fix by having the driver save the hostname that was registered with FDMI. The driver then runs a heartbeat action that will check the hostname. If the name changes, reregister the FMDI data. The hostname is used in RSNN_NN, FDMI RPA and FDMI RHBA.

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.
