@Frank: The commits are not yet available, but we expect them in time for the kernel FF in March

The 'fix' is available on the s390 feature branch already:

https://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git/commit/?h=features&id=ad0faae6ceab7d138dddf9a58eab7151c519e0d3

and if you have a look into this - it is a petty change within a struct exposed to userspace. This feature bug is more for tracking than a real code change.

[Frank Heimes (fheimes)]

I see: "s390/zcrypt: introduce ctfm field in struct CPRBX" it's really pretty manageable.
I'll just wait until 6.3 is opened and it (probably) lands there.
We still have a bit time until Kernel feature freeze.
I'll make sure to have it in in-time.

[Frank Heimes (fheimes)]

Fix is in 'linux-next' since next-20230216.
