badblocks_set(9)

✨ badblocks_set(9) ✨

okay so this one is from the Kernel API Manual, and it's lowkey one of my fave little functions because it's just doing honest bookkeeping work 💅

---

🌸 NAME 🌸

badblocks_set — add a range of bad blocks to the table. that's it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

bool badblocks_set (struct badblocks *bb , sector_t s , sector_t sectors
, int acknowledged );

like look at that signature. it's giving "i know exactly what i'm doing" 🔥

---

💖 ARGUMENTS 💖

• bb — the badblocks structure that holds all the badblock information. the main character of this whole situation 👑
• s — first sector to mark as bad. where the chaos starts ✨
• sectors — number of sectors to mark as bad. how far the chaos spreads 😭
• acknowledged — whether to mark the bad sectors as acknowledged. yes/no, that's the whole question 🫶

---

⭐ DESCRIPTION ⭐

so here's the tea: this might extend the table, or it might contract it if two adjacent ranges can be merged. either way, the algorithm is not out here guessing — we binary-search to find the 'insertion' point, then decide how best to handle it from there. ngl, that's kind of iconic of it 🧚

---

🌈 RETURN 🌈

• true : success 🎉
• false : failed to set badblocks (out of space) 💀

and fr fr, a partial setting will be treated as failure. so no half-slay, it's all or nothing bestie 🙈

that's the whole page bestie, mwah 💋 — from ./block, stamped October 2026, and yeah the page really is called badblocks_set(9) in case you forgot already 😌
