Currently default read buffers that is allowed in a group is 0. grpcfg will be configured to max read buffers that IDXD can support if the group's allowed read buffers value is 0. But 0 is an invalid read buffers value and user may get confused when seeing the invalid initial value 0 through sysfs interface. To show only valid allowed read buffers value and eliminate confusion, directly initialize the allowed read buffers to IDXD's max read buffers. User still can change the value through sysfs interface.

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.
