From 8f920d5e29f86d3425a68e1c3bc264d1f6f55112 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 15 Jul 2008 14:06:48 -0400 Subject: lockd: eliminate duplicate nlmsvc_lookup_host call from nlmsvc_testlock nlmsvc_testlock calls nlmsvc_lookup_host to find a nlm_host struct. The callers of this functions, however, call nlmsvc_retrieve_args or nlm4svc_retrieve_args, which also return a nlm_host struct. Change nlmsvc_testlock to take a host arg instead of calling nlmsvc_lookup_host itself and change the callers to pass a pointer to the nlm_host they've already found. We take a reference to host in the place where nlmsvc_testlock() previous did a new lookup, so the reference counting is unchanged from before. Signed-off-by: Jeff Layton Signed-off-by: J.
