From: Trond Myklebust <trond.mykleb...@primarydata.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 2fc193cf924ea6eb74f6a0cf73b94b2e62938ae5 upstream.
The callback handler xs_error_report() can end up propagating an EPIPE
error by means of the call to xprt_wake_pending_tasks(). Ensure that
xprt_connect_status() does not automatically convert this into an
EIO error.
