This is closely related to the memory technology devices Linux subsystem (MTD), so this new piece of software is from drivers/mtd/ubi. In short, UBI is kind of LVM layer but for flash (MTD) devices. It makes it possible to dynamically create, delete and re-size volumes. But the analogy is not full. UBI also takes care of wear-leveling and bad eraseblocks handling, so UBI completely hides 2 aspects of flash chips which make them very difficult to work with: 1. wear of eraseblocks; 2. bad eraseblocks. There is some documentation available at: http://www.linux-mtd.infradead.org/doc/ubi.html http://www.linux-mtd.infradead.org/faq/ubi.html The sources are available via the GIT tree: git://git.infradead.org/ubi-2.6.git (stable) git://git.infradead.org/~dedekind/dedekind-ubi-2.6.git (devel) One can also browse the GIT trees at http://git.infradead.org/ This is the third iteration of the post which has fixed most of the stuff pointed to previously.
