From df95e7f0d93e2fa776b168eac798a16a1e361022 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 12 Dec 2014 16:02:20 -0500 Subject: [PATCH] Btrfs: abort transaction if we don't find the block group We shouldn't BUG_ON() if there is corruption. I hit this while testing my block group patch and the abort worked properly.
