Complexity analysis of this sort is decades old. McCabe complexity is from 1976. So it's not like no one has done something like this before. Some papers which have done a complexity analysis of the Linux kernel are: http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=html&identifier=ADA403525 http://oai.dtic.mil/oai/oai?verb=getRecord&metadataPrefix=ht... and http://www.cs.huji.ac.il/~feit/papers/MCC12ICPC.pdf http://www.cs.huji.ac.il/~feit/papers/MCC12ICPC.pdf . For more examples, see https://scholar.google.com/scholar?q=complexity+of+the+Linux+kernel+McCabe&btnG= https://scholar.google.com/scholar?q=complexity+of+the+Linux... . The documentation includes an example of running the complexity program on itself. http://www.gnu.org/software/complexity/manual/complexity.html#Example-Output http://www.gnu.org/software/complexity/manual/complexity.htm... If it's that interesting to you, why not do it for yourself and report the results.
