Stale comments above.

Otherwise looks fine to me.

If creating a new btrfs works for btrfs/196, I wonder if we could merge
the two tests into one test, firstly create a new fs & degraded mount,
then wipefs & degraded mount.

Thanks,

  Its better if they are separate. The workout is already looping for
  different raids. Per experiences from btrfs/011 it gets harder to
  debug with testing different cases in one test case. Can I keep them
  separate?

  V2 is being sent out in a while.

Thanks, Anand
