From abefa55ac1f8cb8fb8cb4d7e8d619dc0859181ab Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 24 Apr 2013 16:40:05 -0400 Subject: [PATCH] Btrfs: check return value of commit when recovering log We need to check the return value of the commit in case something goes wrong, otherwise we could end up going down the line and doing more stuff (like orphan cleanup) before we notice we should have errored out. We need to do this before we free up the log_tree_root since the caller will handle all of that.
