This is a merge from 10.2, but the 10.2 version of this will not be pushed into 10.2 yet, because the 10.2 version would include backports of MDEV-14717 and MDEV-14585, which would introduce a crash recovery regression: Tables could be lost on table-rebuilding DDL operations, such as ALTER TABLE, OPTIMIZE TABLE or this new backup-friendly TRUNCATE TABLE. The test innodb.truncate_crash occasionally loses the table due to the following bug: MDEV-17158 log_write_up_to() sometimes fails
