I happen to use it, because it's fast, but the former maintainer has stated on l-k that he and
IBM have no interest in maintaining JFS for Linux, and nobody is working on it at all.

Like the below post says, JFS is fast and stable and widely ignored.  I use it for PostgreSQL
data volumes on fast RAIDs and find that it outperforms everything.  It's reputed to have
long-term fragmentation problems but I haven't personally seen those.

uhg... do you have a link?

Either way, if BTRFS becomes widely used I think its chances are a lot better if Oracle
abandons it. JFS is not very widely used.

In the xfs/jfs/reiser3/ext{3,4} generation of filesystems, they were all pretty roughly
comparable, but I don't think there's any plausible competition for BTRFS on Linux looking at
what's likely to be available in 2009+.

To clarify, this is what Dave Kleikamp, the maintainer, wrote in February on the JFS discussion list:

I guess it depends on what he means by "actively". There is not much in the way of active development, but I think I do a reasonably good job of keeping up with changes in the mainline kernel and responding to and fixing bugs. Some hard-to-diagnose bugs do fall through the cracks.
