[PATCH v2 0/2] s390x/pv: Add support for asynchronous teardown for reboot

Posted by Claudio Imbrenda 1 year, 4 months ago

The first patch is just a minimal header update to compile the second
patch; it can be safely discarded once the Linux headers are updated to
6.2.

The second patch adds support for asynchronous teardown of protected
guests when rebooting. First the existing guest is prepared for
asynchronous teardown, the rebooted guest will be able to continue
immediately, while a background thread actually performs the necessary
cleanup.

v1->v2:
* remove useless snprintf and pass the name of the thread directly
* make the name of the thread more understandable
