Add rg_data0, rg_data and rg_bitbytes to struct gfs2_rgrp. The fields are identical to their counterparts in struct gfs2_rindex and are intended to reduce the use of the rindex. For now the fields are only written back as the in-memory equivalents in struct gfs2_rgrpd are set using values from the rindex. However, they are needed at this point so that userspace can make use of them, allowing a migration away from the rindex over time. The new fields take up previously reserved space which was explicitly zeroed on write so, in clusters with mixed kernels, these fields could get zeroed after being set and this should not be treated as an error.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
