Provide a callback function to the CDAT parser in order to parse the Device Scoped Memory Affinity Structure (DSMAS). Each DSMAS structure contains the DPA range and its associated attributes in each entry. See the CDAT specification for details. The device handle and the DPA range is saved and to be associated with the DSLBIS locality data when the DSLBIS entries are parsed. The xarray is a local variable. When the total path performance data is calculated and storred this xarray can be discarded.

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.
