create_single_sg(9)

💅 create_single_sg(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, you've got a scatterlist and a buffer, and you just need them to meet. that's the whole vibe of this function. it's the little matchmaker of the SG world. 🎀

---

✨ SYNOPSIS ✨

struct scatterlist * create_single_sg (struct scatterlist *sg , void
*buf , int buflen );

like, that's the whole signature. no notes. iconic. 🫶

---

🌸 ARGUMENTS 🌸

• sg — the destination SG list 💫 (the place your entry is going, your destination if you will)
• buf — the data 📦 (the actual payload, the main character)
• buflen — the data length 📏 (how much of that data we're talking about)

---

💖 DESCRIPTION 💖

it returns the next free entry in the destination SG list. that's it. that's the function. lowkey perfect, highkey useful. the matching is done, the entry is pointed at the data, and you get handed back where to go next. no cap. ✨
