From 5dc07727f86b25851e95193a0c484ea21b531c47 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 11 Aug 2005 16:25:35 -0400 Subject: [PATCH] [PATCH] RPC: Rename xprt_lock Clean-up: Replace the xprt_lock with something more aptly named. This lock single-threads the XID and request slot reservation process. Test-plan: Compile kernel with CONFIG_NFS enabled.
