xfs: create incore rt allocation groups [v5.5 04/10] Add in-memory data structures for sharding the realtime volume into independent allocation groups. For existing filesystems, the entire rt volume is modelled as having a single large group, with (potentially) a number of rt extents exceeding 2^32 blocks, though these are not likely to exist because the codebase has been a bit broken for decades. The next series fills in the ondisk format and other supporting structures. With a bit of luck, this should all go splendidly. Signed-off-by: Darrick J. Wong <djwong@kernel.org>
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 reStructuredText 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.
