Pull more xfs updates from Darrick Wong:
"Except for the timestamp struct renaming patches, everything else in
here are bug fixes:
- Rename the log timestamp struct.
- Remove broken transaction counter debugging that wasn't working
correctly on very old filesystems.
- Various fixes to make pre-lazysbcount filesystems work properly
again.
- Fix a free space accounting problem where we neglected to consider
free space btree blocks that track metadata reservation space when
deciding whether or not to allow caller to reserve space for a
metadata update.
- Fix incorrect pagecache clearing behavior during FUNSHARE ops.
- Don't allow log writes if the data device is readonly"

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.
