[PATCH] ufs: make fsck -f happy
ufs super block contains some statistic about file systems, like amount of
directories, free blocks, inodes and so on.
UFS1 hold this information in one location and uses 32bit integers for such
information, UFS2 hold statistic in another location and uses 64bit integers.
There is transition variant, if UFS1 has type 44BSD and flags field in super
block has some special value this mean that we work with statistic like UFS2
does. and this also means that nobody care about old(UFS1) statistic.
So if start fsck against such file system, after usage linux ufs driver, it
found error: at now only UFS1 like statistic is updated.
This patch should fix this. Also it contains some minor cleanup: CodingSytle
and remove unused variables.
