From b7993cebb841b0da7a33e9d5ce301a9fd3209165 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 14 Apr 2013 11:42:00 -0400 Subject: SUNRPC: Allow rpc_create() to request that TCP slots be unlimited This is mainly for use by NFSv4.1, where the session negotiation ultimately wants to decide how many RPC slots we can fill.
