[PATCH 3.12 106/122] SUNRPC: Ensure xprt_connect_status handles all potential connection errors

From: Jiri Slaby
Date: Tue Feb 17 2015 - 06:44:55 EST


From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>

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

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

commit 0fe8d04e8c3a1eb49089793e38b60a17cee564e3 upstream.

Currently, xprt_connect_status will convert connection error values such
as ECONNREFUSED, ECONNRESET, ... into EIO, which means that they never
get handled.
