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.[ Reply to This | Parent | # ]
