    Description

      Summary:
      		 
      ========
      		 
      When binlog is on, innodb redo log will write at innodb prepare stage,
      		 
      and binlog will write at binlog commit stage.
      		 
       
      		 
      Actually, write innodb redo log could move to binlog commit stage only
      		 
      if it write before binlog. Then, redo log and binlog can use original
      		 
      binary group commit logic to improve performance.

            The patch is understood, but it can't be applied so directly as MariaDB's binlog group commit is different
            from mysql's which the patch is for.
            The work is postponed at least until March when higher priority tasks will be done.
