We don't do patch review on bugzilla (and it's not really practical). You can send it as a reply to your message (so it's threaded correctly) by mentioning the Message-Id of your message: git send-email --in-reply-to AM6PR10MB21504CBD56291D9C255739E1EF1F0@AM6PR10MB2150.EURPRD10.PROD.OUTLOOK.COM Simon
