Hi All,
I found two doubtful points in thin-provisioning-tools,
which might need your help to provide some opinions:
1. thin_check doesn't open metadata and data space maps.
It uses the core space_map to open the mapping_tree,
instead of the data space map. Is that legal?
(Although block_time_ref_counter was never used during tree traversal)
2. Class mapping_tree_detail::ll_damage_visitor should not be used to traverse
a single_mapping_tree. This class was designed for two-level data mapping tree,
or the top-level data mapping tree (i.e., mapping_tree and dev_tree types).
It generates missing_devices while visiting a damage with zero-length-path,
which is not semantically suitable for single_mapping_tree.
Thanks,
Ming-Hung Tsai
