Btrfs: prepare block group cache before writing Writing the block group cache will modify the extent tree quite a bit because it truncates the old space cache and pre-allocates new stuff. To try and cut down on the churn lets do the setup dance first, then later on hopefully we can avoid looping with newly dirtied roots. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com>
