From 7a9a7b774fd543467313894fe53bc7dcc47d5708 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Sun, 18 May 2014 13:47:14 -0400 Subject: [PATCH] SUNRPC: Fix a module reference issue in rpcsec_gss We're not taking a reference in the case where _gss_mech_get_by_pseudoflavor loops without finding the correct rpcsec_gss flavour, so why are we releasing it?
