* Enable FITRIM on the realtime device.
* Introduce byte-based grant head log reservation tracking instead of
physical log location tracking.
This allows grant head to track a full 64 bit bytes space and hence
overcome the limit of 4GB indexing that has been present until now.
* Fixes
- xfs_flush_unmap_range() and xfs_prepare_shift() should consider RT extents
in the flush unmap range.
- Implement bounds check when traversing log operations during log replay.
- Prevent out of bounds access when traversing a directory data block.
- Prevent incorrect ENOSPC when concurrently performing file creation and
file writes.
- Fix rtalloc rotoring when delalloc is in use
* Cleanups
- Clean up I/O path inode locking helpers and the page fault handler.
- xfs: hoist inode operations to libxfs in anticipation of the metadata
inode directory feature, which maintains a directory tree of metadata
inodes. This will be necessary for further enhancements to the realtime
feature, subvolume support.
- Clean up some warts in the extent freeing log intent code.
- Clean up the refcount and rmap intent code before adding support for
realtime devices.
- Provide the correct email address for sysfs ABI documentation.

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.
