It's possible you are posting to the wrong linux-crypto list.  Though this is in fact the original linux-crypto list, it is primarily concerned with loop-aes.

Some bright spark thought it a really good idea to start another list with exactly the same name, which is intended for mainline kernel crypto afaik:
