Subject: [PATCH] Treat Linux 4 (and greater) as Linux 2.6/3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In an age where Linux version numbers are determined by Google+ polls,
it’s clear that they aren’t going to be very useful for marking major
API compatibility boundaries like they were in the days of 2.2/2.4.
