"It is quite educating to look at exactly what’s growing
per directory in therms of SLOC. If you take a look at top 8
directories within the kernel you can notice that:
* drivers (/drivers) are a huge part and grow very quickly
* arch (/arch) started growing around 2.6.5
* network (/net) started growing around 2.6.13
* filesystems (/fs) do not grow that much but they have their
bursts like with 2.6.16, 2.6.19, where bulks of code where
merged
* network (/net) which stareted growing at 2.6.16, now outgrew
sound (/sound)"
