    [PATCH] ufs: truncate negative to unsigned fix
    
    During ufs_trunc_direct which is subroutine of ufs::truncate, we try the 
first
    of all free parts of block and then whole blocks.  But we calculate size of
    block's part to free in the wrong way.
    
    This may cause bad update of used blocks and fragments statistic, and you 
can
    got report that you have free 32T on 1Gb partition.
