kho_block_set_restore(9)

💖 kho_block_set_restore(9) 💖

okay bestie, welcome to the Kernel API Manual — this one's a section 9 page and it's literally about bringing a block set back to life from a physical address. yes, we're doing kernel stuff today, put your hair up 🎀

---

✨ NAME ✨

kho_block_set_restore — restore a block set from a physical address. that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

int kho_block_set_restore (struct kho_block_set *bs , u64 head_pa );

look at that signature, she's gorgeous, no notes 💅 (copy it exactly please, this is not a drill)

---

✨ ARGUMENTS ✨

• bs — the block set you're restoring. the main character of this function, honestly 👑
• head_pa — the physical address of the first block header. like the starting point of the whole quest 🗺️

---

✨ DESCRIPTION ✨

so here's the tea: this function restores a serialized block set from a given physical address. that's the whole plot 🔥

but listen — and this is important, bestie — the caller is responsible for making sure the block set bs has already been allocated and initialized before calling this function. not the function's problem, not the kernel's problem, your problem. do your homework before you show up 🙈

fr fr, no cap — don't call this on an uninitialized bs. that's not a vibe, that's a bug. ⚠️

---

✨ RETURN ✨

• 0 on success — slay, it worked 💖
• a negative errno on failure — it's giving sad girl hours 😭
