      Description

      Within ~1 min test on current 10.6 with default log_warnings level I'm getting in the error log ~8500 records like this:

      2021-03-22  2:58:35 8 [Note] InnoDB: Cannot close file ./test/FTS_00000000000012c8_00000000000015f9_INDEX_1.ibd because of 0 pending operations and pending fsync

      ...
      

      10.5 seems to produce only those with "0 pending operations", so there are less of them, but still, ~4000 in a few-minute test. And these ones (with zero) are especially confusing.

      I think if these are real problems which a user needs to take care of, there should be warnings or errors (and given the persistence, maybe we are missing at least a debug assertion or something); and if these are just technical notifications, there shouldn't be so many of them.
