acomp_request_set_dst_sg(9)

✨ acomp_request_set_dst_sg(9) ✨

okay so you're in the Kernel API Manual bestie, and this page is all about acomp_request_set_dst_sg — literally the glow-up moment where your async compression request finally gets told where to put its output 🎀

---

🌸 NAME 🌸

acomp_request_set_dst_sg — sets destination scatterlist 💅

---

⭐ SYNOPSIS ⭐

void acomp_request_set_dst_sg (struct acomp_req *req , struct
scatterlist *dst , unsigned int dlen );

no cap, that's the whole signature. three args, void return, we love a low-drama function 🫶

---

🦋 ARGUMENTS 🦋

• req — the asynchronous compress request. the main character of this whole operation fr fr ✨
• dst — pointer to the output buffer scatterlist. yes bestie, it's a scatterlist, not just one buffer, we're being fancy today 💅
• dlen — size of the output buffer. gotta tell it how much room it's working with 🎀

---

🧚 DESCRIPTION 🧚

Sets the destination scatterlist required by an acomp operation. that's it, that's the vibe — you're handing the request its output scatterlist so the acomp op knows where the compressed (or decompressed, depending on which direction you're going 👀) data should land 🌈

lowkey iconic that it's one job and it does it, periodt.

🎀 friendly reminder that the destination side has a whole little family — _dst_dma, _dst_nondma, _dst_folio, and this _dst_sg one. pick the one that matches what you're actually handing it, iykyk 😭
