As mentioned earlier, discarding data can be done either by issuing an explicit discard or implicitly by reusing the LBA. Metadata block_groups see much more frequent reuse due to well it being metadata. So instead of explicitly discarding metadata block_groups, just leave them be and let the latter implicit discarding be done for them. For mixed block_groups, block_groups which contain both metadata and data, we let them be as higher fragmentation is expected.
