blk_crypto_...ecrypt_endio(9)

💅 blk_crypto_...ecrypt_endio(9) — Kernel API Manual 🎀

okay so bestie, we're in the Kernel API Manual today and this page is literally about one tiny function that does a very specific little job. no cap, it's short, but it's important, so let's get into it 💖

---

✨ NAME ✨

blk_crypto_fallback_decrypt_endio — the one that queues a bio for fallback decryption 🦋

---

🌸 SYNOPSIS 🌸

void blk_crypto_fallback_decrypt_endio (struct bio *bio );

that's it. that's the whole signature. she's lowkey minimal and we respect it 👑

---

🎀 ARGUMENTS 🎀

• bio — the bio we're queueing. that's the whole vibe. she's the main character here 💅

---

💜 DESCRIPTION 💜

okay so picture this: we gotta restore bi_private and bi_end_io, and then queue the bio for decryption into a workqueue.

and why are we doing the queue thing instead of just, like, doing it right there? because — and this is the important part, don't skip it — this function will be called from an atomic context 😭 so you literally cannot just go off and do the decryption inline. that's not the move. into the workqueue it goes, periodt ✨

fr fr, the atomic-context thing is the whole reason this function exists. respect the constraint or the kernel will simply not have a good time 💀

🦋 SEE ALSO 🦋

• Kernel file ./block/blk-crypto-fallback.c — the whole source, go read her 🌈
• blk_crypto_fallback_bio_prep(9) — the sibling function, iykyk 🫶

---

and that's the page bestie!! 🧚 from ./block (that's the source, mwah) and dated October 2026 — stay caffeinated, stay cryptographically safe, and remember: atomic context means no blocking, no exceptions 💖💅⭐🍓
