Rosenblum and Ousterhout: a log-structured file system

What changed

Implemented Sprite LFS with sequential log segments and segment cleaning.

Scientific scope

The record is the exact two-author 1992 ACM Transactions on Computer Systems paper. Its performance evidence is bounded to Sprite LFS workloads and hardware, and it does not absorb earlier logging, later flash-aware systems or every implementation contributor.
