> The conversion of in-tree users is fairly straightforward. It is pretty much - but a related question (that you totally don't have to answer if you don't want to think about this). I'm going to have to (continue) backport(ing) this code to older kernels for customer support, and I prefer making as few modifications to the code as possible and putting all the logic into the external backports project. Do you think it'd be feasible at all to somehow override the aead_request_set_crypt() and aead_request_set_ad() functions or so to do something that works on older kernels (and thus older crypto subsystems) or do you think I just shouldn't bother looking at that and just add ifdefs to "undo" your changes in this series on older kernels? johannes -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
