From 557134a39c8d2ab79d8b8d53438e03e29feb5ec4 Mon Sep 17 00:00:00 2001 From: Andy Adamson Date: Wed, 1 Apr 2009 09:21:53 -0400 Subject: nfs41: sessions client infrastructure NFSv4.1 Sessions basic data types, initialization, and destruction. The session is always associated with a struct nfs_client that holds the exchange_id results. Signed-off-by: Rahul Iyer Signed-off-by: Andy Adamson Signed-off-by: Benny Halevy [remove extraneous rpc_clnt pointer, use the struct nfs_client cl_rpcclient. remove the rpc_clnt parameter from nfs4 nfs4_init_session] Signed-off-by: Andy Adamson Signed-off-by: Benny Halevy [Use the presence of a session to determine behaviour instead of the minorversion number.] Signed-off-by: Andy Adamson [constified nfs4_has_session's struct nfs_client parameter] Signed-off-by: Benny Halevy [Rename nfs4_put_session() to nfs4_destroy_session() and call it from nfs4_free_client() not nfs4_free_server(). Also get rid of nfs4_get_session() and the ref_count in nfs4_session struct as keeping track of nfs_client should be sufficient] Signed-off-by: Alexandros Batsakis [nfs41: pass rsize and wsize into nfs4_init_session] Signed-off-by: Andy Adamson [separated out removal of rpc_clnt parameter from nfs4_init_session ot a patch of its own] Signed-off-by: Benny Halevy [Pass the nfs_client pointer into nfs4_alloc_session] Signed-off-by: Andy Adamson Signed-off-by: Benny Halevy [nfs41: don't assign to session->clp->cl_session in nfs4_destroy_session] [nfs41: fixup nfs4_clear_client_minor_version] [introduce nfs4_clear_client_minor_version() in this patch] Signed-off-by: Benny Halevy [Refactor nfs4_init_session] Moved session allocation into nfs4_init_client_minor_version, called from nfs4_init_client. Leave rwise and wsize initialization in nfs4_init_session, called from nfs4_init_server.
