The SVr4 src has definitely left the building.
``If I don't badly recall, the allegation of SCO was that the SMP code used in Linux was handed over by IBM when Linux' SMP support simply sucked.''

I agree that the SMP and NUMA support was sucking in the past. However in the recent years things have changed wildly. There are OSS projects out there (e.g., Linux Scalability Project, Kernel Performance Project, NUMA Project, etc.) that are dedicated in making Linux SMP and NUMA efficient.

Actually, the 2.6 kernel comes with several NUMA enhancements, including the O(1) scheduler, CPU sets, etc. And ALL these have NO connection to init. UNIX source. I know of at least one vendor (SGI) which has ported many of these decent NUMA mechanisms to their 2.4 kernel (ALtix).

I think now that Linux 2.6 has started moving passed older UNIX kernels or it is very close at least (IRIX, AIX, etc.)

Nevertheless, it makes very little sense to copy verbatim code that is 20+ years OLD and is thus severely outdated. Even the regular UNIX src tree has changed so much from the original AT&T licensed code that it must be almost unencumbered. I suspect that only the STREAMS pipelining code maybe still there from SVr4 but even this one was implemented by Mentat and is used by several vendors.

Ideas, algorithms, APIs and behavior models were used from UNIX but the actual src is simply nonsense.
