And I guess we can just pass parameters with register after remove an
argument,
otherwise need to push/pop stack with more than six parameters for x64.

I doubt it makes any notable performance change.

I think it is called in the IO path (process_read and process_write) ...

BTW, do you agree if the 'usr' can be dropped from rdma_ev given it is
always
same as 'data + data_len'?

in the current form, yes, usr  can be dropped. we can add later if
there is a need.
