      Description

      Email report from Oli Sennhauser
      —
      I think I found a docu bug in the change_buffer docu.
      https://mariadb.com/kb/en/innodb-change-buffering/

      Innodb_buffer_pool_pages_dirty: Number of dirty pages in the Change Buffer.
      contradicts:

      Number of InnoDB buffer pool pages which contain dirty (modified) data
      https://mariadb.com/kb/en/innodb-status-variables/#innodb_buffer_pool_pages_dirty

      Number of dirty pages in the Change Buffer. -> Number of dirty pages in the Buffer Pool.

      And thus IMHO the whole chapter (Change Buffer Related Status Variables) becomes obsolete?

      According to MySQL Docu: Change Buffer Related Status Variables can be found in the SHOW ENGINE INNODB STATUS output, in I_S.INNODB_METRICS and I_S.INNODB_BUFFER_PAGE
