Subject: [CRYPTO] api: Use structs for cipher/compression
X-Git-Tag: v2.6.21-rc1~83^2~65^2~2^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;ds=sidebyside;h=78a1fe4f242cbe6b4578e072b75e171b92745afa;p=linux-2.6

[CRYPTO] api: Use structs for cipher/compression

Now that all cipher/compression users have switched over to the new
allocation scheme, we can get rid of the compatility defines and use
proper structs for them.
