__task_lazy_mmu_mode_pause(9)

💅 __task_lazy_mmu_mode_pause(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual 🎀 and today's main character is __task_lazy_mmu_mode_pause — yes it's a mouthful, yes it ate, let's get into it 🫶

---

✨ NAME ✨

__task_lazy_mmu_mode_pause — literally the function that pauses the lazy MMU mode for a task 💅

---

🌸 SYNOPSIS 🌸

void __task_lazy_mmu_mode_pause (struct task_struct *tsk );

like that's it, that's the whole signature, no cap 😌

---

🦋 ARGUMENTS 🦋

• tsk — the task to check 👀 that's the one you're handing over, she's the subject of the whole operation

---

⭐ DESCRIPTION ⭐

So what does she actually do? She pauses the lazy MMU mode of tsk. Simple, iconic, done 🔥

okay but here's the important lore 🧚 this function only operates on the state saved in task_struct. So if you're trying to pause the lazy MMU mode of the current task, you do not call this — you call lazy_mmu_mode_pause instead, periodt 💖

and ngl, this one's got a whole audience: it's intended for architectures that implement the lazy MMU mode 🏛️ and it must not be called from generic code. like, that's not a suggestion bestie, that's a hard no 🙈
