From eb18860e1385bfc7f08fcb7ba362e4a5156c8324 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 14 Mar 2008 14:18:37 -0400 Subject: [PATCH] NLM: NLM protocol version numbers are u32 Clean up: RPC protocol version numbers are u32. Make sure we use an appropriate type for NLM version numbers when calling nlm_lookup_host(). Eliminates a harmless mixed sign comparison in nlm_host_lookup().
