From 7cb852dfc858e9ab092cbbfcb3e57bae4aa7f56a Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Tue, 10 Sep 2013 18:44:31 -0400 Subject: [PATCH] NFSv4.1: fix SECINFO* use of put_rpccred Recent SP4_MACH_CRED changes allows rpc_message.rpc_cred to change, so keep a separate pointer to the machine cred for put_rpccred.
