What we have now is two implementations that don't support SGs. In terms of users we have one in kernel i.e module verifier which doesn't need SGs and proposed user space interface, which is going to copy data from/to user because the buffers are so small that it is cheaper to copy than to use the splice/vmsplice calls. To be honest I don't see any benefit in adding SG support. -- 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
