I don't see why we need this change, the original looks correct.
So there are the two distinct parts to the fs-grow procedure. The first
is writing to the rindex and statfs files -- this is what was missing in
gfs2, and I'm ignoring that part for now.
The second part is gfs detecting that a grow took place and updating its
list of rg's. I don't think this part needs any changing at all, it
should work the same way it always has -- this is what I'm focussing on.
