In commit f467cad95f5e3, I added the ability to force a recalculation of
the filesystem summary counters if they seemed incorrect. This was done
(not entirely correctly) by tweaking the log code to write an unmount
record without the UMOUNT_TRANS flag set. At next mount, the log
recovery code will fail to find the unmount record and go into recovery,
which triggers the recalculation.
What actually gets written to the log is what ought to be an unmount
record, but without any flags set to indicate what kind of record it
actually is. This worked to trigger the recalculation, but we shouldn't
write bogus log records when we could simply write nothing.
Fixes: f467cad95f5e3 ("xfs: force summary counter recalc at next mount")

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.
