Dave Woodhouse (RedHat) is travelling over from Cambridge on Sunday to give October's talk at 6.30pm in the Computer Lab.

The Journalling Flash File System

JFFS is a log-structured filesystem designed by Axis Communications AB in Sweden specifically for use on flash devices in embedded systems. It is aware of the restrictions imposed by flash technology and operates directly on the flash chips, thereby avoiding the inefficiency of having two journalling filesystems on top of each other.

This presentation will give an overview of the restrictions imposed by flash technology and hence the design aims of JFFS, and the implementation of both JFFS and the improvements made in version 2, including compression and more efficient garbage collection.
