page_ext_put(9)

✨ page_ext_put 💅

okay so bestie, this is a page_ext_put(9) situation and honestly? it's the cleanup era of page extended information. think of it as the "bye bye, we're done here" of the page_ext world 🎀

---

🌸 SYNOPSIS 🌸

void page_ext_put (struct page_ext *page_ext );

---

🫶 ARGUMENTS 🫶

• page_ext — the page extended information you got back from page_ext_get. yes, that exact one. it's giving "return the thing you borrowed" energy 💖

---

🦋 DESCRIPTION 🦋

so like… the page extended information of the page may not be valid after this function is called. lowkey important, highkey a vibe check: once you call page_ext_put, treat that info as gone. don't come back for it, don't text it, it's not answering 😭

---

⭐ RETURN ⭐

None. literally nothing. it's not about the return value, it's about the closure 🧚

---

💜 CONTEXT 💜

Any context with corresponding page_ext_get is called. that's it, that's the rule — matching set, no cap ✨

reminder bestie: after page_ext_put the extended info may not be valid. that's not a maybe-maybe, that's a real caveat — don't use it after 💀
