BTW: you can always select the compressor using the compr= mount option. Also for the default filesystem.
Putting it at the end does not harm but IMHO the use is little. But for the sake of completes, I agree with you. Can you send a follow-up patch?

Can you please share more details? I'm interested what CPU this was.
