From 23475d66bd8600e0c5353f86c1b74f68df27bdb5 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Thu, 11 Aug 2005 16:25:08 -0400 Subject: [PATCH] [PATCH] RPC: Report connection errors properly when mounting with "soft" Fix up xprt_connect_status: the soft timeout logic was clobbering tk_status, so TCP connect errors were not properly reported on soft mounts. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP.
