That concept is, decoupling "extent management" from other file system features. The resulting vision is a situation in which persistent storage is obtained with a small suite of extent allocation syscalls analogous to malloc and free, but persistent, and these services are both provided and used by compliant FSes, resulting in the ability to have one file system slosh around to various spindles in various on-disk formats. I don't plan on being in Boston in August but if I went that is what I would try to present on. -- Is it the time when there isn't time to discuss but there is time to act yet?
