s5p_hash_update(9)

💜 s5p_hash_update(9) — like, the Kernel API Manual page you actually wanna read

okay so bestie, welcome to the glow-up of s5p_hash_update(9), straight out of the Kernel API Manual. This is the Samsung s5p hash update situation and we're gonna get into it ✨

---

🌸 NAME 🌸

s5p_hash_update — literally just processes the hash input data, no cap 💅

---

🦋 SYNOPSIS 🦋

int s5p_hash_update (struct ahash_request *req );

that's it. that's the signature. she's short and she's iconic 🎀

---

🍓 ARGUMENTS 🍓

• req — the AHASH request. that's the whole vibe. it's the thing you're handing over to get hashed 🫶

---

⭐ DESCRIPTION ⭐

okay so here's the tea 👑: if the request will fit in the buffer, it just copies it and returns immediately — like, done, bye, no drama 💅.

but if it won't fit? then it enqueues it with OP_UPDATE. that's the whole thing. that's the function. lowkey elegant ngl ✨

---

🔥 RETURN 🔥

bestie, you gotta see s5p_hash_final below for that — it's giving "the answer lives in another manpage" 😭
