Linux isn't hosted on github, it's hosted on their own cgit instance: https://git.kernel.org/

There was a short period of time, back in 2011, when kernel.org went down for some time (from late August: https://lwn.net/Articles/457142/ to early October: https://lwn.net/Articles/461465/), so Linux was temporarily hosted on github. After that, the repository on github was kept as a mirror of the official kernel.org repository, but it's a one-way flow.
