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 The UBI tree has been in -mm for a few releases now and we would like to see it in the mainline. We have several groups using the code now and it has proved to be fairly stable thus far. We've also got some feedback from people outside the community. The structure of the UBI code is very simple. Whole UBI consists of units. Each unit has one .c file which implements it and one .h file which defines the interface of this unit. So I've split the UBI code so that there is a distinct patch for each unit header and implementations. Plus there are several patches like JFFS2 support, user-space-visible headers, etc. To realize what is the unit responsible for, glance at its header - there is a short description.
