[ Upstream commit630785bfbe] The deprecation of the 'attr2' mount option in 6.18 wasn't entirely successful because nobody noticed that the kernel never printed a warning about attr2 being set in fstab if the only xfs filesystem is the root fs; the initramfs mounts the root fs with no mount options; and the init scripts only conveyed the fstab options by remounting the root fs. Fix this by making it complain all the time. Cc: stable@vger.kernel.org # v5.13 Fixes:92cf7d3638("xfs: Skip repetitive warnings about mount options") Signed-off-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 reStructuredText 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.
