    [XFS] This fix prevents bulkstat from spinning in an infinite loop. · c2cba57e

    Here 'agino' increments through the inodes in an allocation group. At the
    end of the innermost 'for' loop it will hold the value of the next inode
    to look at (ie the first inode in the next cluster/chunk). Assigning
    'lastino' to 'agino' resets it to the last inode in the last inode cluster
    we just looked at. This causes us to look up the very same cluster and
    examine all the inodes all over again, and again, and again...
    
    We also want to set 'lastino' for the cases when we're not interested in
    the inode so that the next call to bulkstat won't re-examine the same
    uninteresting inodes.
