Here are some graphs made from the current Linux source code as taken from Linus github’s mirror. They show the evolution over versions of Linux (from 2.6.12 to 3.19 excluding all release candidates “-rc[0-9]+”) in term of size, number of files, number of lines of codes or authors and commiters. The last one shows that Linux releases are somehow pretty linear. Theses images are licenced CC-BY-SA (Olivier DELHOMME). Upon demand.
