  Fix Bug#39939 DROP TABLE/DISCARD TABLESPACE takes long time in
  buf_LRU_invalidate_tablespace()

  branches/5.1: ha_innobase::delete_all_rows(): In response to a user asking
  <http://forums.innodb.com/read.php?4,215,215> why DELETE FROM t is not
  mapped to TRUNCATE TABLE t as it is in MyISAM, note in a comment that
  DELETE is transactional while TRUNCATE is not.
