ubifs_branch_hash(9)

💅 ubifs_branch_hash(9) — the kernel API manual, bestie edition 🎀

okay so this is ubifs_branch_hash, a kernel API manual page, and it's like... extremely straightforward, which honestly? iconic of it. no cap.

---

✨ NAME ✨

ubifs_branch_hash — returns a pointer to the hash of a branch 🦋

---

🌸 SYNOPSIS 🌸

u8 * ubifs_branch_hash (struct ubifs_info *c , struct ubifs_branch *br );

that's it. that's the whole call. she's not complicated, she's just serving ✨

---

💖 ARGUMENTS 💖

• c — the UBIFS file-system description object. yes the whole file system, bestie, she's right there 🫶
• br — the branch you want the hash from. give her the branch, she gives you the hash. slay 🌈

---

⭐ RETURN ⭐

so what do you actually get back? a pointer to the hash of a branch 💅

and here's the little lore drop: since the key already is a dynamically sized object, we cannot use a struct member here. so no cute little field, no fixed slot — you get a pointer instead. lowkey the only option, and honestly it ate 😭

heads up bestie: this page genuinely has no warnings, no deprecated flags, no exit statuses, and no environment variables. what you see is what you get. don't go looking for drama that isn't there 🙈

okay and finally, the sign-off 💜 — this page lives in the kernel source at ./fs/ubifs, and its date stamp is October 2026. that's the whole vibe check, go get that hash pointer, ily, bye 🧚✨🍓
