that same OS/2 JFS was backported to AIX as JFS2, I believe.
When JFS was implemented on OS/2 it was based on JFS on AIX. After that, JFS for Linux and JFS2 was based on the same code. Not sure I would say "backported", but there you go....
There are many differences between JFS and JFS2 on AIX and the latter is better in many ways... more tuning and support for shrinking.
