💖 trace_softirq_exit(9) — Kernel API Manual 💖

Okay bestie, welcome to the softirq-exit corner of the kernel docs. This page is short, sweet, and very blink-and-you'll-miss-it. ✨

🌸 NAME 🌸

trace_softirq_exit — called immediately after the softirq handler returns. 💅

🦋 SYNOPSIS 🦋

void trace_softirq_exit (unsigned int vec_nr );

🎀 ARGUMENTS 🎀

• vec_nr — softirq vector number, periodt. 💖

✨ DESCRIPTION ✨

When used in combination with the softirq_entry tracepoint, we can determine the softirq handler routine. That's the whole vibe: pair this one with softirq_entry and you've got what you need to figure out the softirq handler routine. 🔥
