From dead28da8e3fb32601d38fb32b7021122e0a3d21 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 20 Mar 2006 13:44:23 -0500 Subject: SUNRPC: eliminate rpc_call() Clean-up: replace rpc_call() helper with direct call to rpc_call_sync. This makes NFSv2 and NFSv3 synchronous calls more computationally efficient, and reduces stack consumption in functions that used to invoke rpc_call more than once. Test plan: Compile kernel with CONFIG_NFS enabled. Connectathon on NFS version 2, version 3, and version 4 mount points.
