set_lli_eol(9)

💅 set_lli_eol — Kernel API Manual ✨

okay so bestie, welcome to set_lli_eol(9) 🎀 this one lives in the Kernel API Manual and it's lowkey iconic: it's the lil function that tells a descriptor "you're the end of the line, babes, the transfer stops with you" 🛑

---

✨ NAME ✨

set_lli_eol — set end-of-link to descriptor so it will end transfer 💅

Like, the whole job is: mark that descriptor as the eol one so the transfer wraps up right there. no cap.

---

🦋 SYNOPSIS 🦋

void set_lli_eol (struct at_desc *desc , unsigned int i );

that's it, that's the whole signature — two args, zero returns, void girlie through and through ✨

---

🌸 ARGUMENTS 🌸

• desc — the descriptor 💖 it's either a single one or one sitting at the end of a chain, and it's the one the chain is gonna end on. main character energy fr fr.
• i — the index of the atmel scatter gather entry that's chilling at the end of the chain 🔥 that's the one being marked, iykyk.

periodt 💜 that's the whole page. no hidden options, no sneaky defaults, just a tiny function doing its one (1) job and doing it well.
