# Test plan:
# A. Check that ACL statements are not vulnerable to the lock-wait-timeout.
#    NOTE: In case of getting rid of the table-level MDL-locks for the ACL
#    statements, the deadlock error should also be checked.
# B. Check that SET PASSWORD commits a transaction.
# C. Check the ACL statement behavior in case when multiple user accounts are
#    given.
# D. Check the ACL statement behavior in case of SE failures.
# E. Check it's not possible to change the privilege table storage engine
#    via ALTER TABLE. Also check that harmless ALTER TABLE (change SE to InnoDB
#    when it's already InnoDB) is allowed.
# F. Upgrade/downgrade tests.
