Re: kern/54541: kernel panic using "zfs diff"

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?
