In commitfe08cc5044we reworked the valid superblock version checks. If it is a V5 filesystem, it is always valid, then we checked if the version was less than V4 (reject) and then checked feature fields in the V4 flags to determine if it was valid. What we missed was that if the version is not V4 at this point, we shoudl reject the fs. i.e. the check current treats V6+ filesystems as if it was a v4 filesystem. Fix this. cc: stable@vger.kernel.org Fixes:fe08cc5044("xfs: open code sb verifier feature checks") Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Darrick J.

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.
