[PATCH] [240/275] SUNRPC: Never reuse the socket port after an xs_close()

[Andi Kleen]

2.6.35-longterm review patch.  If anyone has any objections, please let me 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
