finish_reservation(9)

💅 finish_reservation(9)

ok so this is a page from the Kernel API Manual bestie, and it's a short one but it's lowkey kind of iconic. buckle up 🎀

---

✨ NAME ✨

finish_reservation — finish a reservation. yes that's it. that's the whole name section. she's concise 💅

---

🦋 SYNOPSIS 🦋

void finish_reservation (struct ubifs_info *c );

like literally one argument, no return value, void all the way through. no cap, she does the thing and leaves 🔥

---

🌸 ARGUMENTS 🌸

• c — the UBIFS file-system description object. that's your whole context bestie, everything lives in there 🫶

---

💖 DESCRIPTION 💖

so this function finishes journal space reservation ✨ that's the vibe. it wraps up the reservation you made earlier, closes the loop, ties the little bow 🎀

and then the original page just goes "It must be called after" and like… stops 😭 that's genuinely where the sentence ends on the page — no word on what comes after, so i'm not gonna make anything up. if you need the follow-up, go read the source, bestie, because the manpage is out here leaving us on read 💀

ngl it's giving cliffhanger energy but the rule of the land is we keep every detail and add none, so here we are 🧚
