What enables Tcp_Vegas in the Kernel?

I would like to know if someone could tell me in the tcp.c file which function/line of code that enables the congestion avoidance algorithm.

I believe that this function/line of code enables the congestion avoidance algorithm, specifically the tcp_reno.

Code:

tcp_register_congestion_control(&tcp_reno);

I ask because I want to enable the tcp_vegas in the Kernel. I assume if that I put tcp_vegas such like this:

Code:

tcp_register_congestion_control(&tcp_vegas);

I would enable tcp_vegas congestion avoidance algorithm in the tcp_vegas.c file, right?

The tcp.c file I am referring to is the one that you can download from the Kernel website. I have attached it as well
