That was SCO's claim. In fact, the JFS in Linux derives from the OS/2 version of JFS, which was developed by a different team within IBM, without reference to the AIX source code – so the Linux version of JFS has nothing to do with anything that SCO might have had rights to.

This doesn't detract from the fact that, whatever its technical merits, JFS's market share in the Linux world is considerably lower than that of competing file systems such as the ext family or SGI's XFS.

If IBM was interested in JFS as anything more than a migratory path from AIX, they would have published material to support the case. For instance, benchmarks showing how JFS performs in comparison to XFS or Ext4. They would also have worked with vendors like Red Hat and Novell to make it a supported filesystem. I don't think they pushed for JFS. and contributor agreements

JFS used to be great (and of the first journaling filesystems in Linux, IIRC), but it has been completely neglected by IBM (and others) for many years, so it is essentially abandoned. and contributor agreements

JFS isn't abandoned. It is still actively maintained. There's no new development, just bug fixes, but it's definitely not abandoned. and contributor agreements

I am sorry, I didn't know that. and contributor agreements

Reiserfs 3 was the first journaling filesystem in Linux. Not JFS
