UBIFS: fix a bug in empty space fix-up (2012-07-20 10:13:27 +0300)
----------------------------------------------------------------
Fix a bug in UBIFS free space fix-up 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.
