ubifs_tnc_remove_dh(9)

💅 ubifs_tnc_remove_dh(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ you're literally reading ubifs_tnc_remove_dh(9) and it's a whole lil function that lives in the kernel, no cap 🫶

---

🌸 NAME 🌸

ubifs_tnc_remove_dh — remove an index entry for a "double hashed" node. periodt. that's the whole job 💅

---

✨ SYNOPSIS ✨

int ubifs_tnc_remove_dh (struct ubifs_info *c , const union ubifs_key
*key , uint32_t cookie );

it returns an int, it takes three things, and yes the signature is exactly that — don't come for me, I copied it character for character 🔥

---

🎀 ARGUMENTS 🎀

• c — the UBIFS file-system description object. your whole filesystem's identity, basically the main character 👑
• key — key of node. it's a const union ubifs_key *, so like… look but don't touch 🙈
• cookie — node cookie for collision resolution. a uint32_t. when two things hash to the same spot, this lil cookie is the tiebreaker 🍓

---

🦋 DESCRIPTION 🦋

Returns 0 on success or negative error code on failure. that's it, that's the whole vibe check 💀 zero means slay, negative means something went sideways 😭

ngl this one's a short page but it ate, and it's giving "small function, big responsibilities" 💀 don't forget the negative return codes exist, they WILL humble you 😭
