ent was introduced to assist with fixing MDEV-6916, an
issue introduced in MariaDB 5.2 where the view algorithms were swapped
compared to their MySQL on disk representation. It checks whether the view
algorithm is correct. It is run as part of mariadb-upgrade, and should not
normally be required in regular use.

By default it corrects the checksum and if necessary adds the mariadb-version
field. If the optional FROM MYSQL clause is used, and no mariadb-version field
is present, the MERGE and TEMPTABLE algorithms are toggled.

By default, REPAIR VIEW statements are written to the binary log and will be
replicated. The NO_WRITE_TO_BINLOG keyword (LOCAL is an alias) will ensure the
statement is not written to the binary log.
