I went back to ls_first after finding the flag broke the old code path for
gfs_controld, and making it work involved changing more of the old code
that I wanted to in this patch.  We can go back and reorganize how some of
that old code works (and remove ls_first), in a subsequent patch.

This is now msleep_interruptible(500), I couldn't get around adding some
sort of delay here.  If we think of another way to delay this I'll be
happy to try it.

I've finished and tested the rest of the changes.
