xs_udp_timer(9)

🌸 NAME 🌸

Okay bestie, meet xs_udp_timer(9) — straight from the Kernel API Manual. It's the function that gets called when a retransmit timeout occurs on a UDP transport. Literally the “oops, UDP said timeout, time to handle it” moment. 💅

✨ SYNOPSIS ✨

void xs_udp_timer (struct rpc_xprt *xprt , struct rpc_task *task );

🎀 ARGUMENTS 🎀

• xprt — the controlling transport. The transport in charge, basically. 👑
• task — the task that timed out. Poor thing. 😭

🦋 DESCRIPTION 🦋

After a retransmit timeout has occurred, this function adjusts the congestion window. That's the whole vibe: timeout happens → congestion window gets adjusted. Periodt. 🔥
