commit b73494fa9a304ab95b59f07845e8d7d36e4d23e0 upstream. Quotas aren't (yet) supported with realtime, so we shouldn't allow userspace to set up a realtime section when quotas are enabled, even if they attached one via mount options. IOWS, you shouldn't be able to do: # mkfs.xfs -f /dev/sda # mount /dev/sda /mnt -o rtdev=/dev/sdb,usrquota # xfs_growfs -r /mnt 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 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.
