Darrick J. Wong 890d7dfff7 xfs: don't write a corrupt unmount record to force summary counter recalc
commit 5cc3c006eb45524860c4d1dd4dd7ad4a506bf3f5 upstream.

[ Modify fs/xfs/xfs_log.c to include the changes at locations suitable for
  5.4-lts kernel ]

In commit f467cad95f, 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: f467cad95f ("xfs: force summary counter recalc at next mount")

README

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.
