tcp_lp_remote_hz_estimator(9)

okay so this is tcp_lp_remote_hz_estimator(9), and it lives in the Kernel API Manual — yes, we're doing kernel internals today, bestie. 🫶

✨ NAME ✨

• tcp_lp_remote_hz_estimator — that's the name, the whole name, and nothing but the name. The original description field is literally empty, no cap. 💅

🌸 SYNOPSIS 🌸

literally this signature, character for character:

u32 tcp_lp_remote_hz_estimator (struct sock *sk );

🎀 ARGUMENTS 🎀

• sk — the socket that needs an estimate for the remote HZs. It's the main character here. 💅

🦋 DESCRIPTION 🦋

So this function estimates the remote HZ. The vibe: we keep updating the estimated value as we go. Plot twist: the original TCP-LP implementation only guest it for once and use forever — yes, that's the original text, and we're keeping its chaotic energy. This one keeps that estimate fresh instead of freezing it forever. 🔥
