    fixup! Reduce threading (#685740)
    
    Shrinking a partition containing a reiserfs file system was actually
    corrupting it.  It was first maximising the file system to fill the
    initial larger size and then shrinking the partition.  Example command:
    
        # sh -c 'echo y | resize_resierfs /dev/sda8' -s 1073741823
    
    Fix by including the size specification inside the single quoted command
    passed to the shell to execute.  Also move the size option to before the
    device parameter to match the ordering documented in the manual page.
    Example fixed command:
    
        # sh -c 'echo y | resize_resierfs -s 1073741823 /dev/sda8'
