No. You seem to be the only person who does  _not_ care for efficiency. 
loop-AES has it's own crypto stuff, freeS/WAN has it's own crypto 
stuff. xyz has it's own crypto stuff. That's very efficient, indeed. 
Both from a kernel size and from a developer time pov.

Speed is secondary. Maintainablilty and code auditing is what matters 
here. If more modules use common cryptographic routines instead of 
everyone implementing their own, bugs get fixed faster and the overall 
product is better.

This is something _you_ don't want, obviously. You rather write the 
fivehundreth implementation of AES for kernel space instead of fixing 
the existing stuff. That wouldn't be much of a problem if you did stop 
bashing cryptoAPI. Yes, your code is better. It is even more 
performant. But it is an island solution. We don't need that, see? We 
need something that is _generic_. CryptoAPI is. At least it is more so 
than what other people have come up with. It's a _very_ good sign that 
the ppdd and cipe people start using cryptoAPI. It means that bugs get 
identified. That they are not fixed so fast as one would like is a 
pity. But whining that everyone starts using cryptoAPI doesn't help. 
Sending patches does. Bugging the maintainer to make sure they are 
applied, does.

There's more than disc encryption out there!
