STRUCT SL(9)

💅 struct sl(9) — like, the whole manual, but make it make sense

okay so bestie, welcome to the kernel API manual, section 9 (that's the kernel interfaces girlies ✨). Today's main character is struct sl — and yes, we're doing the struct sl(9) page together, hold my iced coffee 🍓

✨ NAME ✨

struct sl — storage list (SL) 🎀

That's it, that's the name. Short, iconic, to the point. Slay.

🌸 SYNOPSIS 🌸

struct sl {
    struct sl_element element[QDIO_MAX_BUFFERS_PER_Q];
 };

literally the entire shape of it. no cap. 👑

---

🦋 Members 🦋

• element — the SL entries 💖 like, this is the array holding them, and it's sized QDIO_MAX_BUFFERS_PER_Q, which is a whole lot of besties in one list, iykyk.

🌈 SEE ALSO 🌈

okay so there's a whole friend group here, and honestly they're all linked from the kernel file ./arch/s390/include/asm/qdio.h — go say hi to all of them 🫶
