kmemleak_transient_leak(9)

💖 kmemleak_transient_leak(9) — a Kernel API Manual moment 💖

okay so bestie, welcome to the kmemleak_transient_leak page, straight out of the Kernel API Manual. it's a tiny one but she's important, i promise 🫶

---

✨ NAME ✨

kmemleak_transient_leak — mark an allocated object as transient false positive 💅

---

🌸 SYNOPSIS 🌸

void __ref kmemleak_transient_leak (const void *ptr );

---

🎀 ARGUMENTS 🎀

• ptr — pointer to beginning of the object. literally just hand her the start of the block, that's it, that's the whole assignment 🍓

---

🦋 DESCRIPTION 🦋

so here's the vibe: if you call this function on an object, the memory block will not be reported as a leak temporarily. yes, temporarily, she's on a little break, do not perceive her 😭

when does that even happen? say the object is part of a singly linked list and the ->next reference to it gets changed — the tracker can lose sight of it for a sec, and that's exactly the situation this function is for. no cap, it's giving "she's not lost, she's just between references" ✨

heads up: the whole point is that it's transient — this keeps the block out of the leak report for the moment, it's not a permanent "everything is fine" pass, so don't treat it like one 💀
