In addition to Jan's update to _not_ enable discard support I would recommend to completely revert the patch:
7e64db1597fe114b83fe17d0ba96c6aa5fca419a s390/dasd: Add discard support for ESE volumes
to prevent the user from enabling the discard support for DASD devices.
This patch will also be reverted upstream until further clarification.
