[52/55] SUNRPC: Never reuse the socket port after an xs_close()

From: Greg KH
Date: Fri Mar 25 2011 - 19:56:28 EST


2.6.37-stable review patch. If anyone has any objections, please let us know.

------------------

From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>

commit 246408dcd5dfeef2df437ccb0ef4d6ee87805f58 upstream.

If we call xs_close(), we're in one of two situations:
- Autoclose, which means we don't expect to resend a request
- bind+connect failed, which probably means the port is in use
