Subject: Btrfs: release both paths before logging dir/changed extents
From: Josef Bacik <jbacik@xxxxxxxxxxxx>
commit f3b15ccdbb9a79781578249a63318805e55a6c34 upstream.
The ceph guys tripped over this bug where we were still holding onto the
original path that we used to copy the inode with when logging. This is based
on Chris's fix which was reported to fix the problem. We need to drop the paths
in two cases anyway so just move the drop up so that we don't have duplicate
code. Thanks,
