devm_blk_cry...profile_init(9)

💖 devm_blk_cry...profile_init(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes this page lives in section 9 of it, and yes the title up top is genuinely truncated to devm_blk_cry...profile_init(9) because apparently even the kernel gets tired of typing. periodt. 😭✨

---

✨ NAME ✨

devm_blk_crypto_profile_init — it's literally blk_crypto_profile_init() but with resource management energy. the devm version. the one that cleans up after itself. main character behavior fr fr 💅

---

🦋 SYNOPSIS 🦋

int devm_blk_crypto_profile_init (struct device *dev , struct
blk_crypto_profile *profile , unsigned int num_slots );

like, look at that signature. three args. no notes. iconic. 🎀

---

🌸 ARGUMENTS 🌸

• dev — the device that owns the blk_crypto_profile. it's giving parent vibes. 👑
• profile — the actual blk_crypto_profile you're initializing. this is the one getting set up. 🫶
• num_slots — the number of keyslots. how many slots for keys? this many. that's the whole thing. 🔑

---

💜 DESCRIPTION 💜

so this is "Like blk_crypto_profile_init, but…" — and that but is the whole point, bestie: it also causes blk_crypto_profile_destroy to be called automatically on driver detach. you don't have to remember to tear it down yourself. the kernel handles it. no cap, it's giving main character energy and also good memory hygiene. 🧚✨

---

⭐ RETURN ⭐

0 on success — slay. 💖

or else a negative error code — not slay. 😭 check it. always check it.
