From 0556d1a6958ba15659ac2089ebc0a3c5e71f08a8 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sat, 5 Dec 2009 15:03:20 -0500 Subject: [PATCH] NFSv41: nfs4_reset_session must always set NFS4CLNT_SESSION_DRAINING Otherwise we have no guarantees that other processes won't start another RPC call while we're resetting the session.
