Daniel Phillips has announced the prototype design of a new linux filesystem (implementation has only begun). The most interesting thing seems to be a different way of implementing versioning: "Unlike the currently fashionable recursive copy on write designs with one tree root per version, Tux3 stores all its versioning information in the leaves of btrees using the versioned pointer algorithm. This method promises a significant shrinkage of metadata for heavily versioned filesystems as compared to ZFS and Btrfs".

This is entirely a function of the GPL licensing of Linux, and has nothing to do with the licensing of ZFS: Apple is also working on ZFS as well, and there's no conflict there between whatever they're linking to that's proprietary and not released to the general public, and the rest of the code (BSD license, I believe).
Everything in life has a price: in the GPL license, you end up being restricted from using someone else's closed code because of an insistence on license purity, while with MIT/BSD the price you pay is there's no guarantee that you'll get any of the interesting changes, but you can use it (or anyone else) anywhere without a big deal. The question is: what are your goals, and what price are you willing and able to pay, because both licenses may have advantages to you, and also both may have advantages to you, all as a matter of context.
