ASYNCHRONOUS COMPRESSION API(9)

💅 ASYNCHRONOUS COMPRESSION API 💅

ok so you're in the kernel API manual, bestie — this page is all about the Asynchronous Compression API, and it's living over in ./include/crypto. slay.

✨ Asynchronous Compression API ✨

So here's the vibe: the Asynchronous Compression API is what you use with algorithms of type CRYPTO_ALG_TYPE_ACOMPRESS — and if you go peek at /proc/crypto, those show up listed as type "acomp". that's the whole tell, fr fr. 🦋

ngl this page is short because it's really a hub — the actual details live in the functions below. go read those, iykyk.
