DML transactions on FK-child tables also get table locks on FK-parent tables. If there is a DML transaction holding such a lock, and a TOI transaction starts, the latter BF-aborts the former and puts itself into a waiting state. If at this moment another DML transaction on FK-child table starts, it doesn't check that the transaction waiting on a parent table lock is TOI, and it erroneously BF-aborts the waiting TOI transaction. The fix: don't roll back high-priority transaction waiting on a lock in InnoDB, instead roll back an incoming DML transaction. Signed-off-by: Julius Goryavsky <julius.goryavsky@mariadb.com>
