HP releases AdvFS under GPL

K. S. Kyosuke writes: The battle for the "next-gen Linux file system" might have just become a little fiercer. Hewlett-Packard have just released their AdvFS file system under GPL. There is a press release on the HP web site, but the Wikipedia entry sports less PHB talk. The reaction of Sun and Oracle (each with their own advanced FS initiative, ZFS and Btrfs, respectively) to this might be interesting.
