Subject: [PATCH 3.12 107/122] SUNRPC: Handle connect errors ECONNABORTED and EHOSTUNREACH

From: Trond Myklebust <trond.myklebust@...marydata.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit df2772700c6ee706be7b2fd16c6bf2c1bf63cda0 upstream.

Ensure that call_bind_status, call_connect_status, call_transmit_status and
call_status all are capable of handling ECONNABORTED and EHOSTUNREACH.
