Last time I tried formatting with a rt device (a month ago) the kernel crashed,
as soon as I created an inode, so I guess we ought to warn people that this
feature is severely bitrotted.

What /is/ the official status of XFS RT?  Most sane distros (looking right at
you, Ubuntu) disable kernel support, so I guess:

------------------------------------------------------------------------
WARNING: The realtime feature is not well maintained.  Use with caution.
