Is a Berkeley license included in Linux? This is a broader issue than just this piece of code, it applies to anything from Linux that was borrowed from BSD.

Is a Berkeley license included in Linux?

Yes, it is. Those parts of Linux that were taken from BSD are supposed to include a notice acknowledging the source (it's a condition of the license).

The BSD license is less restrictive than the GPL: it doesn't require redistribution in source form. That's why you will find it in many operating systems, including Windows. The TCP/IP networking code is a common example.
