Just an FYI, your GH account doesn't seem to be linked to your commit email. E.g. https://github.com/rust-lang/libc/commit/bdc4b7df37ec8bbac325ddd6cdba712a0abe3bcd.patch is authored by you, but bdc4b7d doesn't link to your user.

Not a problem of course, just letting you know in case you want to update it :)

Thanks for letting me know, fixed it! I was accidentally using the same Git config for both internal and external repositories. 😞
