Having the branches would be beneficial for kernel developers as well,
e.g. on multiple occasions I've spent time hunting down non-existent KVM
bugs, only to realize my base kernel was stale with respect to kvm-unit-tests.

My thought was to have a mostly-unmaintained branch for each major kernel
version, e.g. snapshot a working version of kvm_unit_tests when the KVM
pull request for the merge window is sent, and for the most part leave it
at that. I don't think it would introduce much overhead, but then again,
I'm not the person who would be maintaining this :-)
