STRUCT SLSB(9)

💅 struct slsb(9) — from the Kernel API Manual, bestie 🎀

okay so listen up, we're doing a whole deep dive on struct slsb today and honestly? it's giving "tiny but iconic." ✨

---

🌸 NAME 🌸

struct slsb — the storage list state block, aka SLSB if you're on nickname terms 💖

---

✨ SYNOPSIS ✨

struct slsb {
    u8 val[QDIO_MAX_BUFFERS_PER_Q];
};

that's it. that's the whole struct. no aura-wasting extra fields, just vibes and one very important array 🫶

---

🦋 Members 🦋

• val — the state, per buffer 💫 like, one lil u8 of state for each buffer, all tucked into that array. keeping it cute and keeping it per-buffer, periodt.

🔥 SEE ALSO 🔥

the whole friend group, no one left out fr fr 💜

• Kernel file ./arch/s390/include/asm/qdio.h
• struct qdesfmt0(9)
• struct qdr(9)
• struct qib(9)
• struct slibe(9)
• struct qaob(9)
• struct slib(9)
• struct qdio_buffer_element(9)
• struct qdio_buffer(9)
• struct sl_element(9)
• struct sl(9)
• struct qdio_initialize(9)

like yes, that's a lot of structs, but they're all literally part of the same squad so go read them too, iykyk 💅

---

ngl, QDIO_MAX_BUFFERS_PER_Q is doing all the heavy lifting here — it's the size of val, and that's the tea. if you're confused about it, the qdio.h file up in SEE ALSO is right there waiting for you 🍓

and that's the page!! sourced from ./arch/s390/include/asm, dated October 2026, and yes we're closing with the classic struct slsb(9) because the main character always gets the last word 👑💖 mwah, go forth and state-block responsibly bestie 🧚✨
