[PATCH 0/5] UBIFS: fix failure in dbg_check_space_info

[Artem Bityutskiy]

This patch has to fix the failure in 'dbg_check_space_info()' which
I can reproduce myself with the 'integck' test and which has also been
reported here:

http://lists.infradead.org/pipermail/linux-mtd/2011-April/034647.html

The fix is in the last patch and it is quite trivial. It also describes
the reason for the failure.

Patches 1-4 mostly improve the debugging output which helps to diagnose
the problem quicker. So they are preparational patches.

Artem.
