Dear Jeff,
Really thanks for your reply. we'd want to know could the patch we
delivered, which moves ftrace function ahead the removing APIs, be the
finial patch and will submit in k6.6. If yes, we would try to ask
google owner to patch back the patch in k6.1. Or is there any advice to
show us how to fix it. Thanks again.

Best Regards,
Will Shiu
