Newest loopback (twofish) patch, Where to download them ?

I need to have the Loopback patch (that can use Twofish encryption) for the newest vanilla kernel (2.4.25, 2.4.26.pre_) . On http://ftp.linux.hr/pub/linux/kernel/crypto/v2.4/testing/ there is only old patches (july 2003) for kernel 2.4.21 :-( Is there a site with more updated versions. Thanks in advance Bo
