💅 ubifs_destroy_idx_gc (9) — the Kernel API Manual page, bestie edition ✨

okay so you found the page, welcome to the <purple>Kernel API Manual</purple> section, we're doing UBIFS internals today and honestly it's giving very niche but very iconic 🎀

---

💖 NAME 💖

ubifs_destroy_idx_gc — destroys the idx_gc list. that's it. that's the whole vibe. lowkey the most self-explanatory name in the entire kernel and I respect it fr fr 💅

---

🌸 SYNOPSIS 🌸

void ubifs_destroy_idx_gc (struct ubifs_info *c );

not me pointing out that the signature says void and then the DESCRIPTION starts talking about return values 😭 — I'm just the messenger, bestie, I don't make the rules 🙈

---

🦋 ARGUMENTS 🦋

• c — the UBIFS file-system description object. yeah. that's the one. the whole filesystem, in a struct, right there in your hand 🫶

---

✨ DESCRIPTION ✨

so this function destroys the c->idx_gc list. that's the move. that's what it does 💀

it gets called when unmounting, which is the key detail here — because of that, locks are not needed, and honestly? good for her. no locking, no stress, no drama, just teardown 🧚

and per the page: it returns zero in case of success and a negative error code in case of failure. yes, on a void function. yes, we're all just going to sit with that together. no cap. ⭐
