fs/nfs/nfs4session.c:203:54: warning: ‘cur_seq’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  if (nfs4_slot_get_seqid(tbl, slotid, &cur_seq) == 0 &&
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~
      cur_seq == seq_nr && test_bit(slotid, tbl->used_slots))
      ~~~~~~~~~~~~~~~~~
