tracing_map_destroy(9)

💅 tracing_map_destroy(9) — from the Kernel API Manual, bestie

okay so picture this: it's tracing_map_destroy(9), it lives in the Kernel API Manual, and it is literally the cleanup queen of ./kernel/trace. main character energy, but make it deallocation. 🎀

---

✨ NAME ✨

tracing_map_destroy — Destroy a tracing_map 🌸

---

✨ SYNOPSIS ✨

void tracing_map_destroy (struct tracing_map *map );

---

✨ ARGUMENTS ✨

• map — the tracing_map you're about to destroy 🫶 that's the one, bestie, that's the victim

---

✨ DESCRIPTION ✨

So what it does is, like, it frees a tracing_map along with its associated array of tracing_map_elts. both of them. gone. released. slayed. ✨

⚠️ okay but fr fr listen to me for a sec — callers should make sure there are no readers or writers actively reading or inserting into the map before calling this. no cap. do the vibe check before you call tracing_map_destroy, not after. you literally cannot un-destroy. 😭

that's the whole thing. simple, iconic, devastating. 💅
