GFS2 remembers the last rgrp used for allocations in ip->i_rgd. However, block allocations are made by way of a reservations structure, ip->i_res, which keeps the last rgrp in ip->i_res.rs_rgd, and ip->i_res is kept in sync with ip->i_res.rs_rgd, so it's redundant. Get rid of ip->i_rgd and just use ip->i_res.rs_rgd in its place. Based on patches by Robert Peterson.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
