crypto_register_acomp(9)

💅 crypto_register_acomp — the kernel API manual, but make it make sense 🎀

ok so bestie, we're in crypto_register_acomp(9) territory — that's the kernel API manual section 9, the "kernel internals" zone, and honestly? it's giving "you're building a compression driver and you need the kernel to know about it" energy. no cap. 🦋

✨ NAME ✨

crypto_register_acomp — Register asynchronous compression algorithm 💖

like, you're literally introducing your shiny new async compression algorithm to the kernel. it's a whole debut. main character energy fr. 👑

---

✨ SYNOPSIS ✨

int crypto_register_acomp (struct acomp_alg *alg );

so the function is crypto_register_acomp, it takes exactly one argument, and it hands you back an int. that's it. that's the whole vibe check. ⭐

---

✨ ARGUMENTS ✨

• alg — the algorithm definition 🫶 like, the actual struct describing your implementation. this is your algorithm's little ID card. you hand it over and the kernel goes "ok noted, icon behavior."

---

✨ DESCRIPTION ✨

lowkey the whole point: this function registers an implementation of an asynchronous compression algorithm. 🔥

you pass in your algorithm definition, the kernel registers it, and now the async compression world knows your fave exists. it's not synchronous, babes — asynchronous, meaning it's doing its thing without blocking the way, and that is the moment. 😭✨

---

✨ RETURN ✨

the return value is a whole mood check, so listen up:

• zero on success 🎉 — she worked, she slayed, we love to see it
• error code in case of error 💀 — something went sideways and the kernel is telling you exactly which flavor of sideways

that's it. 0 = good, nonzero = not good. iykyk. 🌸

---

✨ SEE ALSO ✨

• Kernel file ./include/crypto/internal/acompress.h, and struct acomp_alg(9) 🎀 — the struct itself, def go read it
• crypto_unregister_acomp(9) 🦋 — the reverse one, for when you're done and you gotta clean up properly (periodt, always unregister)

---

ngl bestie, if you're registering something, you better remember to unregister it later. the kernel does not forget. neither do i. 💀

---

and that's a wrap, bestie!! 🌈 this little page lives in the source directory ./include/crypto/internal and it's dated October 2026 — so like, future-era kernel wisdom, cute. go forth and register your async compression algorithm, you absolute icon. crypto_unregister_acomp is right there when you need her. mwah. 🫶💜🍓
