Hi Thomas,
I love your patch! Perhaps something to improve:

It would help if you'd actually applied the patches to a tree that had
the required objtool patches as described in 0/n. Or better yet, don't
scrape emails if the 0/n includes a git link which you'll run on anyway.
Hi Peter,
Thanks for the advice, we'll add the check to our cluster,
and sorry for the inconvenience.
Best Regards,
Rong Chen
