Looks OK. Just one question/observation, though. This will make the
quota proc files show up even even quota is not compiled in. Are
there any applications out there that make use of the presence of
these files to determine if quota is configured into the kernel or
I think I just answered my own question - xfstests does exactly this
proc file test in _require_quota(). So I think their presence needs
to be conditional on CONFIG_XFS_QUOTA....
