From 98f98cf571b7b1f34683455a61dae9f35e7222a1 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 14 Apr 2013 11:49:51 -0400 Subject: [PATCH] NFSv4.1: Set the RPC_CLNT_CREATE_INFINITE_SLOTS flag for NFSv4.1 transports This ensures that the RPC layer doesn't override the NFS session negotiation.
