Moving Squashfs over to the crypto API is a good idea.  When the zlib 
crypto module code is in the mainline kernel moving Squashfs, AxFS and 
CRAMFS over will be easy.

Are you planning to do the necessary work to get this (or a subsequent 
version following the comments from Herbert Xu) into mainline?
