From f344f6df4b2baa3e5c553c461735dfaf92f44be7 Mon Sep 17 00:00:00 2001 From: Olaf Kirch Date: Mon, 20 Mar 2006 13:44:08 -0500 Subject: SUNRPC: Auto-load RPC authentication kernel modules This patch adds a request_module call to rpcauth_create which will try to auto-load the kernel module for the requested authentication flavor. For kernels with modular sunrpc, this reduces the admin overhead for the user.
