Only the code IBM placed under the GPL for the file system was never in AIX

I would imagine that the C code for JFS ported from OS/2 to AIX stayed mostly
unchanged. If you have evidence to the contrary, please provide it.

The code IBM placed under the GPL for the file system was and is in AIX
Authored by: xtifr on Sunday, May 26 2013 @ 08:52 PM EDT

JFS2 was/is in AIX. It wasn't developed there, but it's provided for OS/2, AIX and Linux. At least according to Wikipedia (and I have no reason to doubt them).

In the AIX operating system, there exist two generations of JFS filesystem that are called JFS (JFS1) and JFS2 respectively.[1][2] In the other operating systems, such as OS/2 and Linux, only the second generation exists and is called simply JFS.

Note that the SCO Group was also well aware of this. Their (extremely silly, IMO) argument was that because JFS2 had been included in AIX at all, the terms of the SYSV license meant that they had a say in what IBM did with the code. (In other words, a contractual dispute.)

This is one of the reasons that the license clarification published in $echo magazine became such a big deal. It made it pretty clear that AT&T wasn't trying to claim any sort of control over modifications like this.
