Please don't push any new patch to staging because we want to have a

The non-zero check on ret is always going to be false because
ret was initialized as zero and the only place it is set to

Hi Ian,
in the Xen community call we agreed to try to speed up OSStest for

Could you please suspend testing for Xen 4.10 and older (Jan agreed on
that), and disable the Linux kernel tests which are currently failing
(including
