The main thing I envisioned for LinearRAID was to make it so that all 
devices that can have a raid level always do. That makes it possible for 
each device type to use the same calls to convert between disk space and 
usable space regardless of whether raid is used (since it is optional 
for lvm and btrfs). It also means that LVMLogicalVolumeDevice code to 
convert between disk space and usable space will look the same as 
MDRaidArrayDevice code that does the same thing.
