Hi Thomas,

I love your patch! Perhaps something to improve:

If you fix the issue, kindly add following tag as appropriate

All warnings (new ones prefixed by >>):

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,
