STRUCT MV_CESA_REQ_OPS(9)

💅 struct mv_cesa_req_ops(9) — the manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual ✨ we're looking at struct mv_cesa_req_ops(9) today and honestly? she's giving backstage crew energy. nobody claps for her but the whole show falls apart without her 🎀

---

🌸 NAME 🌸

struct mv_cesa_req_ops — CESA request operations. that's it, that's the whole vibe. it's a struct full of function pointers that tell the CESA request machinery how to do its little dance 🩰

---

✨ SYNOPSIS ✨

struct mv_cesa_req_ops {
    int (*process)(struct crypto_async_request *req, u32 status);
    void (*step)(struct crypto_async_request *req);
    void (*cleanup)(struct crypto_async_request *req);
    void (*complete)(struct crypto_async_request *req);
 };

not me copy-pasting this exactly because every character matters — please don't retype it from memory, that's how bugs are born 😭

bestie these four are the whole squad, okay, let me introduce them:

• process — this one handles a request chunk result 💖. it should return 0 if the operation, -EINPROGRESS if it needs more steps, or an error code. yes, those are three very different moods and you have to keep them straight. no cap.
• step — launches the crypto operation on the next chunk 🚀 like "okay next", she's the momentum.
• cleanup — cleans up the crypto request (releases the associated data) 🧹 the "okay everyone go home" friend. lowkey the most important one ngl.
• complete — completes the request, i.e. copies the result or context from sram when needed ⭐. it's the grand finale, the copy-out, the bows.

💀 reminder bestie: these are function pointers. if one's null and something calls it, that's a bad time. iykyk.
