If we don't care and this is the only caller we fix up
x86_read_call_gate not to return a value. It looks like it fails safe
with an empty entry (but also the function x86_read_call_gate needs the
printf removing).
Yes, or maybe we should check if the read was a success, or else call
VM_PANIC("x86_read_call_gate").
Any advice from hvf maintainers?
We didn't have any feedback yet.
Would that be possible for a maintainer to pull the current series as it is?
It's functionnally equivalent, and remove this warning to have a clean
9.2 release on this platform.
