    Btrfs: create the uuid tree on remount rw · 94aebfb2
    Josef Bacik authored
    Users have been complaining of the uuid tree stuff warning that there is no uuid
    root when trying to do snapshot operations.  This is because if you mount -o ro
    we will not create the uuid tree.  But then if you mount -o rw,remount we will
    still not create it and then any subsequent snapshot/subvol operations you try
    to do will fail gloriously.  Fix this by creating the uuid_root on remount rw if
    it was not already there.  Thanks,
