From 38eb76a54d803e6792816623651b1a9cb85f8d01 Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Fri, 3 Apr 2009 08:28:32 +0300 Subject: nfsd41: Add a create session replay cache Replace the nfs4_client cl_seqid field with a single struct nfs41_slot used for the create session replay cache. The CREATE_SESSION slot sets the sl_session pointer to NULL. Otherwise, the slot and it's replay cache are used just like the session slots. Fix unconfirmed create_session replay response by initializing the create_session slot sequence id to 0. A future patch will set the CREATE_SESSION cache when a SEQUENCE operation preceeds the CREATE_SESSION operation. This compound is currently only cached in the session slot table.
