You can send a patch to a mailing list with `git send-email`. You can format it first with `git format-patch` and then send the patch with `git send-email`. Configuring it to use your email server takes a few minutes, and you only have to do it once.

I get the feeling most people who complain about how "clunky" email is have never actually tried to submit a patch to LKML. If I could figure it out when I was a high-school student, a professional developer should be able to figure it out as well.
