blk_crypto_put_keyslot(9)

💖 blk_crypto_put_keyslot(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, the actual kernel docs, and yes, we're gonna have a good time with it. this one's a tiny little function in the block-crypto corner of the kernel and honestly? she's short, she's sweet, she's got one job and she does it. let's get into it ✨

---

🎀 NAME 🎀

blk_crypto_put_keyslot — release a reference to a keyslot. that's it. that's the whole vibe. you're letting go, you're moving on, you're decrementing your little hold on a keyslot. very "thank u, next" of you 💅

---

✨ SYNOPSIS ✨

void blk_crypto_put_keyslot(struct blk_crypto_keyslot *slot);

look at her. gorgeous. returns nothing (void), takes exactly one pointer, causes zero drama. 🦋

---

🌸 ARGUMENTS 🌸

• slot — the keyslot you want to release the reference of, bestie. that's the one. hand her over 🫶

---

🌈 CONTEXT 🌈

Any context. literally any. no locks, no special sleep rules, no "you must be in this one exact function at this one exact moment" nonsense. call it wherever, queen 👑

---

👑 SEE ALSO 👑

like all good friend groups, this function does not exist in a vacuum. here's the whole squad:

• the kernel file ./block/blk-crypto-profile.c and blk-crypto profiles(9)
• blk_crypto_profile_init(9)
• devm_blk_crypto_profile_init(9)
• blk_crypto_keyslot_index(9)
• blk_crypto_get_keyslot(9)
• blk_crypto_reprogram_all_keys(9)
• blk_crypto_derive_sw_secret(9)
• blk_crypto_intersect_capabilities(9)
• blk_crypto_has_capabilities(9)
• blk_crypto_update_capabilities(9)

iykyk — one of these (blk_crypto_get_keyslot(9)) is literally her other half, the one that grabs the reference you're about to put down. balance. symmetry. iconic. ⭐

and that's the page, bestie!! source file lives at ./block, and this little beauty is dated October 2026. go forth and release your references responsibly, mwah 💖💅🎀
