From 48df020aa17ac95a012ff765b0086ede5996b320 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 1 Nov 2007 16:56:53 -0400 Subject: NLM: Fix sign of length of NLM variable length strings According to The Open Group's NLM specification, NLM callers are variable length strings. XDR variable length strings use an unsigned 32 bit length. And internally, negative string lengths are not meaningful for the Linux NLM implementation. Clean up: Make nlm_lock.len and nlm_reboot.len unsigned integers. This makes the sign of NLM string lengths consistent with the sign of xdr_netobj lengths.
