        - try to be more explicit in adding in the non-transactional
          data to the reservation estimate. We must add in for the worst
          case of a log stripe taking us the full distance for a log
          stripe boundary.

fs/xfs/xfs_macros.c - 1.55
        - remove xlog_btolrbb() which has changed and is only
          needed in one place.

fs/xfs/xfs_log_priv.h - 1.101
        - remove xlog_btolrbb() which has changed and is only
