Merge tag 'upstream-3.5-rc8' of git://git.infradead.org/linux-ubifs
Pull UBIFS free space fix-up bugfix from Artem Bityutskiy: "It's been reported already twice recently: http://lists.infradead.org/pipermail/linux-mtd/2012-May/041408.html http://lists.infradead.org/pipermail/linux-mtd/2012-June/042422.html and we finally have the fix. I am quite confident the fix is correct because I could reproduce the problem with nandsim and verify the fix. It was also verified by Iwo (the reporter). I am also confident that this is OK to merge the fix so late because this patch affects only the fixup functionality, which is not used by most users." * tag 'upstream-3.5-rc8' of git://git.infradead.org/linux-ubifs: UBIFS: fix a bug in empty space fix-up
