That's certainly possible in BSD. Just about anybody who writes a
block device driver writes the following line at some time or another:
In the Third Edition (1972) I find:
In Linux the problem is that the kernel structures are so different
that it's difficult to imagine what use imported UNIX code would be.
One area would be in ELF initialization code: the data structures are
the same, and initializing them is a pretty mechanical task. I've
compared code and found similarities. They're not so close that you
could assume they had been copied.
It still seems much more plausible to me that SCO engineers
incorporated Linux code into System V than the other way round.
Firstly the Linux code is easier to get hold of, and secondly the
likelihood that they'd be caught is much smaller.
