Re: [GIT PULL 0/7] KVM: s390: Fixes for 7.2

[Christian Borntraeger <borntraeger@linux.ibm.com>]

Paolo,

I have now more patches in virtio-ccw
Same as pci, mostly triggered by AR review.
sashiko feedback is here
https://sashiko.dev/#/patchset/20260728033022.2658232-1-farman%40linux.ibm.com

Shall I simply send a
tags/kvm-s390-master-7.2-3
tag with those as well?
This would be https://git.kernel.org/pub/scm/linux/kernel/git/kvms390/linux.git/log/

The existing patches from 7.2-2 have been reviewed by sashiko here
https://sashiko.dev/#/patchset/20260723221409.5874-1-alifm%40linux.ibm.com
and
https://sashiko.dev/#/patchset/20260724133943.1664961-1-jhkim%40linux.ibm.com
just fine,
but my pull request itself did not work well with sashiko as it failed to partially
apply my patches and then complained about things that have been fixed in those.


We might even have some more fixes from Claudio this time around, we should probably
then do another pull request early next week. Or do you prefer to wait for those?

Christian
