Replace the static define (ZFCP_DIAG_MAX_AGE) with a per-adapter variable
(${adapter}->diagnostics->max_age). This new variable is exported via
sysfs, along with other, already existing adapter variables, and can both
be read and written. This way users can choose how much time should pass
between refreshes of diagnostic buffers. The default value for the age
remains to be five seconds.
By setting this new variable to 0, the caching of diagnostic buffers for
userspace accesses can also be completely removed.
All diagnostic buffers of a given adapter are subject to this setting in
the same way.

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.
