💅 __ubifs_hash_get_desc(9) 💅

okay so bestie, welcome to the Kernel API Manual page for __ubifs_hash_get_desc(9) — yes that's the whole title, it's giving very "written by someone who names their variables c" energy, and honestly? we respect it. grab a snack, this one's short but iconic 🎀

✨ NAME ✨

__ubifs_hash_get_desc — get a descriptor suitable for hashing a node 🌸

like, it goes and fetches you a hash descriptor. that's the whole job. main character energy honestly 👑

---

🦋 SYNOPSIS 🦋

struct shash_desc * __ubifs_hash_get_desc (const struct ubifs_info *c );

that's it. one function, one argument, returns a struct shash_desc *. no cap 🫶

---

💖 ARGUMENTS 💖

• c — the UBIFS file-system description object. yeah. that's the entire description. it's the filesystem's little info bundle, and the function needs it to do its thing ✨

---

🌈 DESCRIPTION 🌈

okay so here's the tea: this function returns a descriptor suitable for hashing a node. that's the vibe. it hands you back a struct shash_desc * and you go off and hash your node with it 💅

⚠️ important bestie: free after use with kfree. like, you got the descriptor, you used the descriptor, now you kfree it. don't just leave it lying around, that's a leak and leaks are not slay 😭💀

omg wait, almost forgot the sign-off 🫶 this whole page lives in ./fs/ubifs, dated October 2026, and it's serving Kernel API Manual realness from the source/version line. periodt. go hash something and kfree it after, love u bye 💜🎀✨
