Yep, you are right to call this out. My usual setup uses SSH keys for
commit signing, which are not part of the kernel web of trust. I
promise to start signing kernel work with my GPG key soon :)

In the meantime if you trust Github you can verify my signature
against https://github.com/tamird.keys.
