To be honest "block_map" group name does not mean anything to me. - "fallocate" is not really the right name as it does much more than that - "extents" is not the right name as there is not really anything extents specific. - "fsx_fsstress" while this gives information about how it is tested it's not immediately clear what it is good for. So I do not know and frankly I do not care very much about the name of this group so if anyone has a strong opinion about the name feel free to create such group.
