Christian, I took the patch and applied it to what's currently in Eoan (19.10)
master-next.
It applied cleanly and it compiled fine and I installed it in z/VM guest that I
installed on FCP.
Afterwards I was able to enable add. DASDs from there with chzdev:

Got feedback that this problems occurs not only on z/VM 6.4 but also on
7.1, and it indeed seems to be an issue with thin provisioning (LP

with dedicated DASDs. Fix is in progress by IBM.
