Apologies for the delayed response. I'm no longer at Canonical, so I'm
replying here using my new email address.

To be honest, I'm unsure who I should reach out to for a review on this. I
added Yu Zhao to the CC in my original submission, as I thought he would be
the most knowledgeable person regarding this code.
Yu, could you take a look or suggest someone else?

Thanks,

Koichiro
