    Description

      Accessing the filesystem root by its FID fails with EINVAL. It seems that master and 2.3 are affected.

      $ lfs path2fid /mnt/lustre
      [0x200000007:0x1:0x0]
      $ ls /mnt/lustre
      $ ls /mnt/lustre/.lustre/fid/0x200000007:0x1:0x0
      ls: cannot access /mnt/lustre/.lustre/fid/0x200000007:0x1:0x0: Invalid argument

            Moving forward beyond the 6209 patch landing, it makes sense to explicitly block rename for the FID_SEQ_DOT_LUSTRE objects, since I don't think it ever makes sense to allow that.

            Assign to John to refresh the patch and remove the (obscure) failing test case.
