hl_mmap_mem_buf_vm_close(9)

💅 hl_mmap_mem_buf_vm_close(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function called hl_mmap_mem_buf_vm_close, and she is literally the cleanup queen of mmap close. no cap. 🎀

---

✨ NAME ✨

hl_mmap_mem_buf_vm_close — handle mmap close 🫶

like, that's her whole job. she handles the close. that's it. that's the vibe. 💅

---

🦋 SYNOPSIS 🦋

void hl_mmap_mem_buf_vm_close (struct vm_area_struct *vma );

she returns nothing (void, icon behavior honestly) and takes exactly one thing. one. single. argument. main character energy tbh. 👑

---

🌸 ARGUMENTS 🌸

• vma — the vma object for which mmap was closed. that's it, that's the whole parameter. she's the struct vm_area_struct * you hand over so the function knows which vma just got its mmap closed. 🐛

---

💖 DESCRIPTION 💖

Put the memory buffer if it is no longer mapped.

that's the entire description and honestly? she ate. 💀 no extra lore, no dramatic backstory — if the buffer is no longer mapped, she puts it. if it's still mapped, she minds her business. the way that this function is short and knows exactly what it wants. periodt. 🌈

ngl this is one of those "small but crucial" functions — she's the cleanup checkpoint when an mmap goes away. don't sleep on her. 😭
