From fd319bb5c7fbe886389e19f8c530ee9a644f9619 Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Wed, 13 Jul 2011 19:12:18 -0500 Subject: [PATCH] net/9p: fix client code to fail more gracefully on protocol error commit b85f7d92d7bd7e3298159e8b1eed8cb8cbbb0348 upstream. There was a BUG_ON to protect against a bad id which could be dealt with more gracefully.
