From 1a68d952af5f43032012d26dd0d5164c9e9986bc Mon Sep 17 00:00:00 2001 From: Greg Banks Date: Mon, 2 Oct 2006 02:17:55 -0700 Subject: [PATCH] knfsd: use new lock for svc_sock deferred list Protect the svc_sock->sk_deferred list with a new lock svc_sock->sk_defer_lock instead of svc_serv->sv_lock. Using the more fine-grained lock reduces the number of places we need to take the svc_serv lock.
