💅 ftrace_get_addr_curr(9) 💅

okay so bestie, this is from the Kernel API Manual, section 9, and it’s all about grabbing the call address that’s already chilling there. no cap. 💖

---

✨ NAME ✨

ftrace_get_addr_curr — get the call address that is already there ✨

---

🎀 SYNOPSIS 🎀

unsigned long ftrace_get_addr_curr (struct dyn_ftrace *rec );

---

🦋 ARGUMENTS 🦋

• rec — the ftrace record descriptor, aka the little descriptor bestie we’re working with 🫶

---

🌸 DESCRIPTION 🌸

the address of the trampoline that is currently being called ✨
