I've applied the other two (though I removed the __func__ and __LINE__

easily be found with out them - I should remove all the others).
However I haven't applied this because there doesn't seem to be any
point.
Once your told that main md superblock that there is no bitmap, it
doesn't really matter what data is in the superblock of that
non-existent bitmap - it will never be looked at. Will it?
mdadm could still get nodes and cluster_name after change
bitmap to none, so some cmds like "mdadm -X /dev/sda" could
still see clustered info, it seems a little confused for user.
Thanks,
