“this” is the code that Linus licensed as he did. Only that code. If you use a snippet, that snippet is governed by the license. The license does not magically extend to other code or even to any modifications that have been made since. This is not the GPL.
replyI think nikanj means that this is not a stipulation of the BSD license at all, that's why it's not compatible with what Linus made there.
replyBut the Linus license has no bearing on the rest of the code base at all.
replyThe entire concept of “compatibility” is an artifact of copyleft. In the rest of the license universe, each piece of code is covered by its own license and it does not matter what licenses other code uses.
This license does not apply to the rest of BSD. The BSD license does not apply to this code.
