[PATCH] Btrfs: fix free space cache when there are pinned extents and clusters
...nd see if the current block group has a
cluster and writing out any entries that are in the cluster to the cache, as
well as writing any pinned extents we currently have to the cache since those
will be available for us to use the next time the fs mounts. This patch also
adds a check to the end of load_free_space_cache to make sure we got the right
amount of free space cache, and if not make sure to clear the cache and re-cache
the old fashioned way. Thanks,
