JFFS2

I'd like to see some more info on JFFS2, the compression algorithm (or algorithms) that will be used, and ideally, some data on how well various files might be expected to compress with examples. Some photos, diagrams, xml, python code, etc.

JFFS2 Is the Journalling Flash File System version 2, jffs2 is a log-structured file system for flash memory devices and has support for NAND devices, also Hard links and compresion algoritms like zlib, rubin and rtime.
