Currently DHT hashes the file name and not the entire path.

See, callers of dht_hash_compute in source (pretty much 
dht_layout_search) to which loc->name is passed, which is the file name 
and not the entire path.

Are you referring to something else in your request? Meaning, you want 
/myfile, /dir1/myfile and /dir2/dir3/myfile to fall onto the same 
bricks/subvolumes and that perchance is what you are looking for?
