Abstract:
   This document updates RFC8881, Network File System (NFS) version 4
   minor version 1, by adding two operations to prevent the client from
   destroying session when getting the reply of a mis-ordered request
   with NFS4ERR_SEQ_MISORDERED.

   In NFSv4 minor version 1, sequence ID is used to ensure that the size
   of the needed reply cache is tightly bounded.  If the server gets a
   mis-ordered request, the client will often break the session and
   establish a new session with the server.  This approach results in a
   significant burden on the client and the server.  During the process
   of session rebuilding, IO performance will be affected.  This is
   especially troublesome when network latency is substantial, as, for
   example when client and server are in different locations.  This
   document will propose extensions to NFSv4 that would allow client
   reconnection to be dispensed with.
