ftrace_kill(9)

🎀 ftrace_kill(9) — Kernel API Manual 🎀

okay so bestie, welcome to the group chat for ftrace_kill(9) from the Kernel API Manual. It’s giving “panic mode but make it ftrace.” 💅

---

✨ NAME ✨

ftrace_kill — kill ftrace. literally that’s the name, no cap. 💀

---

🌸 SYNOPSIS 🌸

void ftrace_kill (void );

---

🎀 ARGUMENTS 🎀

• void — no arguments. none. zero. nada. the void is voiding. 🫶

---

💅 DESCRIPTION 💅

This function should be used by panic code. 🚨 It stops ftrace, but in a not so nice way — like, it’s not the graceful little exit, okay?

If you need to simply kill ftrace from a non-atomic section, use ftrace_kill. yes, that’s what the page says, bestie — same name, keeping it exactly as written. 😭
