Browse Source 
Since now we have more layered devices i.e. thin volumes - support
selection of layer via flag.

Version 2.02.89 -
==================================
Rename origin_only parameter to more generic flag use_layer for lv_info().
Thin pools have segment fields thin_count, zero, transaction_id.
Each new created LV volume has creation lv_time and lv_host.
Print data_percent and metadata_percent for verbose lvs.
