[pnfs] [PATCH 0/2] Update seqid and stateid handling to draft 13

[Iyer, Rahul]

The state id handling patch should probably go in. As mentioned in
section 8.2.2, line 8072, the client can use either a 0 stateid seqid or
a specific one.

  8072	   When stateids are sent to the server by the client, it has
two
  8073	   choices with regard to the seqid sent.  It may set the seqid
to zero
  8074	   to indicate to the server that it wishes the most up-to-date
seqid
  8075	   for that stateid's "other" field to be used.  This would be
the
  8076	   common choice in the case of stateid sent with a READ or
WRITE
  8077	   operation.  It also may set a non-zero value in which case
the server
  8078	   checks if that seqid is the correct one.  In that case the
server is
  8079	   required to return NFS4ERR_OLD_STATEID if the seqid is lower
than the
  8080	   most current value and NFS4ERR_BAD_STATEID if the seqid is
greater
  8081	   than the most current value.  

Thanks,
-Rahul
