 src/external/cddl/osnet/dist/lib/libzfs/common/libzfs_diff.c:
    739  static int
    740  setup_differ_info(zfs_handle_t *zhp, const char *fromsnap,
    741      const char *tosnap, differ_info_t *di)
    742  {
    743          di->zhp = zhp;
    744  
    745          di->cleanupfd = open(ZFS_DEV, O_RDWR|O_EXCL);
    746          VERIFY(di->cleanupfd >= 0);
    747  
    748          if (get_snapshot_names(di, fromsnap, tosnap) != 0)
    749                  return (-1);
    750  
    751          if (get_mountpoints(di) != 0)
    752                  return (-1);
    753  
    754          if (find_shares_object(di) != 0)
    755                  return (-1);
    756  
    757          return (0);
    758  }
 
 so cleanupfd=133 should be OK?
