- * We should always include the random number generator, since it's
- * relatively small, and it's most useful when application developers
- * can assume that all Linux systems have it.  (Ideally, it would be
- * best if we could assume that all Unix systems had it, but oh
- * well....)
- * 
- * Also, many kernel routines will have a use for good random numbers,
- * for example, for truely random TCP sequence numbers, which prevent
- * certain forms of TCP spoofing attacks.
