STRUCT KHO_BLOCK_HEADER_SER(9)

💖 struct kho_block_header_ser(9) — Kernel API Manual 💖

okay so bestie, we're looking at struct kho_block_header_ser, and lowkey it's the little header that could. it lives in the Kernel API Manual and it's giving "small but crucial" main character energy. let's get into it 🫶

---

✨ NAME ✨

struct kho_block_header_ser — the header for the serialized data block. yes, that's literally its whole job, and it does it flawlessly 💅

---

🌸 SYNOPSIS 🌸

struct kho_block_header_ser {
    u64 next;
    u64 count;
};

that's the whole struct. two u64s. no cap, that's it. iconic minimalism ✨

---

🎀 Members 🎀

• next — the physical address of the next struct kho_block_header_ser. yup, it points at its sibling. it's a chain, bestie 🔗
• count — the number of entries that immediately follow this header in the memory block. so like, "how many friends am i bringing to the function" energy 🍓

---

🦋 Description 🦋

so picture this: this structure is located at the very beginning of a block of physical memory that's preserved across a kexec. main character placement fr fr 👑

and what does it do? it provides the necessary metadata to interpret the array of entries that follow it. basically it's the translator, the vibes-checker, the "here's how you read the rest of this block" note. without it the entries are just… noise 😭

👑 SEE ALSO 👑

• Kernel file ./include/linux/kho/abi/block.h
• KHO Serialization Blocks ABI(9)
• KHO_BLOCK_SIZE(9)

💜 quick vibe check: next is a physical address, not some virtual thing — don't come for me, that's straight from the source 🙈

---

and that's the whole page, bestie! this one's from ./include/linux/kho/abi, dated October 2026 — go forth and interpret those entries correctly 💖✨🎀
