HP has announced that they will open source the AdvFS under the second version of the GPL. AdvFS is a mid-90's file system that is used by the Tru64 UNIX operating system. The Wikipedia page on AdvFS provides the necessary background information and feature set of the AdvFS file system.

Its not clear if they'll integrate it in linux.
In case its not clear, this is a GPLv2 technology release, not an actual port to Linux. We're hoping that the code and documentation will be helpful in the development of new file systems for Linux that will provide similar capabilities, and perhaps used to make tweaks to existing file systems. We'll get the tests posted soon.
(from http://lkml.org/lkml/2008/6/23/188)
But in http://advfs.sourceforge.net/ you can read that they're releasing two generations of advfs source code: "The first generation is the version that is currently shipping on Tru64 which represents a well tested enterprise quality file system that has been deployed worldwide for many years. The second generation is a port [to Linux] that was completed a few years ago but never productized."
So it's not clear that they're doing anything with this code. For now, they've just packed up the source and put it in a website. But how useful would be to release this code if they're not planning to port it to linux?

This is excellent news. Let's hope it's implemented in the Linux kernel.
I also hope the Linux implementation will be compatible with the Tru64 implementation so that we don't have another XFS-like on disk incompatibility.
