💅 iommu_pages_list_splice(9) 💅

okay bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, this is our bonding era 🫶

---

✨ NAME ✨

iommu_pages_list_splice — literally just: put all the pages in list from into list to. that's it. that's the whole thing. icon behaviour ngl 👑

---

🌸 SYNOPSIS 🌸

void iommu_pages_list_splice (struct iommu_pages_list *from , struct iommu_pages_list *to );

two lists, one function, zero return value. she's a void queen and she knows it 💅

---

🎀 ARGUMENTS 🎀

• from — the source list of pages. this is the one getting emptied out, she's giving donor energy 🩸
• to — the destination list of pages. this is the one getting all the pages delivered straight to her. main character receiving gifts energy 🎁

---

🦋 DESCRIPTION 🦋

so here's the tea, and it's important tea: from must be re-initialized after calling this function if it is to be used again. ⚠️

like, not "should", not "maybe", must. she's been through something (the splice), and if you try to use her again without re-initializing first, that's on you, not on me. consider this your official warning do not skip the re-init 💀
