<sod>The kernel changes made in year 2007 have been submitted by over 1900 developers, which may be a significant underestimate because developers working in teams usually count as one. It is generally assumed that the community of Linux kernel developers comprises 5000 or 6000 members; also, {{As of|2013|lc=yes}}, the 3.10 release of the Linux kernel had 15,803,499 lines of code. Without smart project management, it would not be possible to maintain development of such a large codebase.<eod>
