Yes, the ioctl needs documentation, though I'm unclear on where's an
appropriate place to put them. The ioctl is not intended for general
consumption, so man-pages.git seems inappropriate. I was thinking
either in xfs_fs.h directly, or perhaps xfsprogs' man pages?
(We don't seem to document the xfs ioctls afaict?)
