This is a bug-fix release. v4 handled static volumes wrong. v6 will address everything that Artem pointed out.
v1: https://lwn.net/Articles/481612/ v2: https://lwn.net/Articles/496586/ v3: Didn't release it to linux-mtd v4: http://article.gmane.org/gmane.linux.kernel/1297626
Changes since v1: - renamed it to UBIVIS (at least in Kconfig) - UBIVIS parameters are now configurable via Kconfig - several bugs have been fixed (design and implementation bugs) - added lots of comments to make the review process easier - made checkpatch.pl happy
Changes since v2: - minor bugs have been fixed - renamed it to UBI fastmap (as Artem requested)
Changes since v3: - changed the on-flash layout (added padding fields, turned the EBA storage into an array) - fixed some corner cases (the protection queue needed some extra work) - removed the data type hint logic - rebased to Artems mtd tree
Changes since v4: - fixed static volume handling (used_ebs and last_data_bytes contained bad values in some cases)
