From 492104c866cb1b62a11393adccb477f5cd2c7768 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 8 Mar 2013 15:41:02 -0500 Subject: [PATCH] Btrfs: return EIO if we have extent tree corruption The callers of lookup_inline_extent_info all handle getting an error back properly, so return an error if we have corruption instead of being a jerk and panicing. Still WARN_ON() since this is kind of crucial and I've been seeing it a bit too much recently for my taste, I think we're doing something wrong somewhere.
