We use different integer types throughout zfcp to store the FSF request ID and related values; some places use 'unsigned long' and others 'u64'. On s390x these are effectively the same type, but this might cause confusions and is generally inconsistent. The specification for the used hardware specifies this value as a 64-bit number, and ultimately we use this value to communicate with the hardware, so it makes sense to change the type of all these variables to 'u64' where we can. The only exception being when we store it in the 'host_scribble' field of a 'struct scsi_cmnd'; for this case we add a build time check to make sure they are compatible.

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.
