Pull ufs fixes from Al Viro:
"Fix assorted ufs bugs: a couple of deadlocks, fs corruption in
truncate(), oopsen on tail unpacking and truncate when racing with
vmscan, mild fs corruption (free blocks stats summary buggered, *BSD
fsck would complain and fix), several instances of broken logics
around reserved blocks (starting with "check almost never triggers
when it should" and then there are issues with sufficiently large
UFS2)"
[ Note: ufs hasn't gotten any loving in a long time, because nobody
really seems to use it. These ufs fixes are triggered by people
actually caring now, not some sudden influx of new bugs. - Linus ]
