From 0d3a34b48c87a374b37d7a21a60d257d076484f3 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 7 Jul 2008 12:18:52 -0400 Subject: SUNRPC: Fix a double-free in rpcbind It is wrong to be freeing up the rpcbind arguments if the call to rpcb_call_async() fails, since they should already have been freed up by rpcb_map_release().
