The code IBM placed under the GPL for the file system was and is in AIX
Authored by: Kilz on Sunday, May 26 2013 @ 09:42 PM EDT
You failed to cite IMHO the relevant section of that Wikipe dia article
In 1995, work began to enhance the file system to be more scalable and to support machines that had more than one processor. Another goal was to have a more portable file system, capable of running on multiple operating systems. After several years of designing, coding, and testing, the new JFS was first shipped in OS/2 Warp Server for eBusiness in April, 1999, and then in OS/2 Warp Client in October, 2000. In December, 1999, a snapshot of the original OS/2 JFS source was granted to the open source community and work was begun to port JFS to the Linux operating system.
So accordig to the source you cited, a new implimentation of the JFS was introduced first in OS2. That was the source of the code that was GPL'd and used in Linux.
In parallel with this effort, some of the JFS development team returned to the AIX Operating System Development Group in 1997 and started to move this new JFS source base to the AIX operating system. In May, 2001, a second journaled file system, Enhanced Journaled File System (JFS2), was made available for AIX 5L.
So the file system came from OS2, was GPL'd and used as the basis of the JFS in Linux, then was ported to AIX.

But as you pointed out it really doesnt matter because AT&T in $echo stated that AT&T laid no claim to the additions licencees made to AIX. So even if SCO had the copyrights, which it has now proved beyond a shadow of a doubt in court are still with Novell, SCO can not lay claim to what IBM added.

So to make a long story short "But the code that was in AIX (JFS1)was not the same code that was placed under the JPL. That came from OS2 (JFS2) that eventually found its way into AIX at a later date.
