Set SO_TCP_NODELAY (disabling the Nagle Algorithm)

[Naruto Nguyen]

Hello everyone,

As I know we have a socket option SO_TCP_NODELAY to disable Nagle
Algorithm, and I found it is implemented in TCP/IP stack at
https://elixir.bootlin.com/linux/v4.4.90/source/net/ipv4/tcp.c#L2401 .
However, I do not know where the source code the Nagle Algorithm is
implemented in kernel. If you know, could you please help me?

Brs, Naruto
