Subject: [PATCH 004 of 13] knfsd: SUNRPC: Don't set msg_name and msg_namelen when calling sock_recvmsg
Date: Fri, 8 Dec 2006 23:02:08 +1100 [thread overview]
Message-ID: <1061208120208.18172@suse.de> (raw)
In-Reply-To: 20061208225655.17970.patches@notabene
From: Chuck Lever <chuck.lever@oracle.com>
Clean-up: msg_name and msg_namelen are not used by sock_recvmsg, so
don't bother to set them in svc_recvfrom.
