The hypervisor provides the available VAS GZIP capabilities such as default or QoS window type and the target available credits in each type. This patch creates sysfs entries and exports the target, used and the available credits for each feature. This interface can be used by the user space to determine the credits usage or to set the target credits in the case of QoS type (for DLPAR). /sys/devices/vas/vas0/gzip/default_capabilities (default GZIP capabilities) nr_total_credits /* Total credits available.

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.
