In eoan we shipped: 57d53162face UBUNTU: SAUCE: Revert "s390/dasd: Add discard support for ESE volumes"
And as it is a SAUCE patch, we continue to ship it, as we don't implicitely drop them: 964ce509e2de Revert "s390/dasd: Add discard support for ESE volumes" Currently if you grep for DASD_FEATURE_DISCARD: $ git grep DASD_FEATURE_DISCARD arch/s390/include/uapi/asm/dasd.h:#define DASD_FEATURE_DISCARD 0x080 drivers/s390/block/dasd_fba.c: dasd_set_feature(cdev, DASD_FEATURE_DISCARD, 1); It is only enabled for the FBA devices. Since the original request to disable DISCARD for ESE volumes, we have not re-enabled them. So what is the purporse of this request? Do you want us to disable it for FBA volumes too? We will not re-enable DISCARD for ESE volumes, until you say it's good again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862749 Title: [UBUNTU 20.04] Thin Provisioning support (disablement or final solution) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1862749/+subscriptions -- ubuntu-bugs mailing list firstname.lastname@example.org https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
