Bug Description

The DASD driver should provide a way to enable auto-quiescing.

Quiesce is a function that tells Linux to stop issuing I/Os to a specific DASD. Resume is the corresponding function that tells Linux to continue issuing I/Os. These are purely Linux-internal functions with no effect on the storage side, except for no new I/Os being issues. Quiesce and resume are functions that are available today in the DASD driver.

Autoquiesce is a function that automatically performs the Quiesce operation on a DASD if a certain event occurs. There is no auto-resume, that is, an external entity will need to resume a DASD.

This item will not make it in time for Ubuntu 23.04. Therefore, we need to postpone to the next release.

Changing target milestone to: 23.10

Thx for the list of commits.

I could see that these are all upstream since 6.4(-rc1).
And with that they are all in Ubuntu-6.4.0-1.1 (I double checked this).

But since we are still at 6.3.0.7.9 in matic as of today, I can only update the status to Fix Committed.
(Once we are on the target kernel release 6.5 I'll update to Fix Released.)

Updating to Fix Released, since we meanwhile have kernel 6.5 in mantic as default.
