ksm_enable_merge_any(9)

💖 ksm_enable_merge_any — the Kernel API Manual, bestie edition 💖

okay so this one lives in section 9 of the Kernel API Manual and it's literally called ksm_enable_merge_any and no cap it does exactly what it says: it adds mm to the mm ksm list and turns on merging for all the compatible VMA's. group-chat summary: "we're merging now, all of us, together." 🫶

---

✨ SYNOPSIS ✨

int ksm_enable_merge_any (struct mm_struct *mm );

that's it. one function, one argument, returns an int. iconic minimalism 💅

---

🎀 ARGUMENTS 🎀

• mm — a pointer to mm (the struct mm_struct). that's the whole vibe. it's the memory map you're about to put on the ksm list. 🦋

---

🌸 DESCRIPTION 🌸

so what happens? it returns 0 on success — and if it's not success? you get an error code back instead. that's the entire contract, and honestly? clean, simple, we love a function that knows itself. 💖

lowkey important: 0 = slay, anything else = error code, so always check your return value bestie, don't just ignore it 🙈
