innodb engine status missing some IO statistics

Details

    Description

      Somewhere between 10.1 and 10.2, some of the IO statistics in 'show engine innodb status' stopped working.

      In 10.1:

      Pending normal aio reads: 0 [0, 0, 0, 0] , aio writes: 0 [0, 0, 0, 0] ,
      ibuf aio reads: 0, log i/o's: 0, sync i/o's: 0

      in 10.2:

      Pending normal aio reads: [0, 0, 0, 0] , aio writes: [0, 0, 0, 0] ,
      ibuf aio reads:, log i/o's:, sync i/o's:

      As you can see there are some zeroes missing.

      thanks
      Jonathan
