Why not using fixed-size fit-all members?
struct ncr_session_input_data {
__u64 data; /* user pointer, cast to/from u64 */
__u32 data_size; /* or __u64? */
};
struct ncr_session_output_buffer {
__u64 buffer;
__u64 result_size_ptr; /* can't this be a direct output member? */
__u32 buffer_size; /* or __u64? */
};
And then get rid of all the COMAPT code paths.
