SCO identifies code?

I've been off the news for a while, and I was wondering if SCO has
provided any details yet of exactly what was supposedly copied into
Linux from Unix System V.  I then read this:


-- quote --
The cameras flashed when SCO attorneys briefly highlighted on screen 
alleged examples of "literal" copyright infringement and improper use of 
derivative works of Unix System V code that appear in Linux 2.4X and 
Linux 2.5X.

While it was difficult to ascertain the exact code being shown on 
screen, attorneys pointed to exact copying of some code from Unix to 
Linux and claimed that IBM improperly donated almost a million lines of 
Unix System V code to the Linux 2.4x and Linux 2.5x kernel that infringe 
on its Unix System V contract with SCO -- and SCO's intellectual 

SCO claimed that much of the core code of Linux including Non-Uniform 
Memory Access, the Read Copy Update for high-end database scalability, 
Journaling File System, XFS, Schedulers, Linux PPC 32 and 64-bit support 
and enterprise volume management is covered by SCO's Unix System V 
contracts and copyrights.

For example, 110,000 lines of Unix System V code for read copy update, 
55,000 lines of NUMA code and more than 750,000 lines of symmetric 
multi-processing code from Unix System V has made its way into Linux, 
attorneys and SCO executives claimed.

SCO owns XFS?

I assume most here agree it's absurd to think you can't have "free" 
software?  Isn't that what SCO is now claiming, that US copyright law 
"supercedes(sic) the GPL" -- so you can't write "free" software?
