commit a24cae8fc1f13f6f6929351309f248fd2e9351ce upstream. If growfsrt is run on a filesystem that doesn't have a rt volume, it's possible to change the rt extent size. If the root directory was previously set up with an inherited extent size hint and rtinherit, it's possible that the hint is no longer a multiple of the rt extent size. Although the verifiers don't complain about this, xfs_repair will, so if we detect this situation, log the root directory to clean it up. This is still racy, but it's better than nothing.

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.
