    Increase the maximum size of the journaled soft-updates journal.
    
    The size of the journaled soft-updates journal should be big enough
    to hold two minutes of filesystem metadata-update activity. The
    maximum size of the soft updates journal was set in the 1990s. At
    the time it was assummed that disk arrays would top out at 16 drives
    and disk writes per drive would top out at 500 per second. Today's
    I/O subsystems are considerably bigger and faster than those limits.
    Thus this delta removes the hard upper limit and lets tunefs(8) and
    newfs(8) set the upper bound based on the size of the filesystem and
    its cylinder groups.
