💅 nand_isreserved_bbt(9) — a Kernel API Manual moment

okay so bestie, welcome to nand_isreserved_bbt(9) from the Kernel API Manual ✨ this one's short and sweet and honestly kind of a serve — it's tagged [NAND Interface] and it does exactly one (1) thing, but it does it iconically 🎀

🌸 NAME 🌸

nand_isreserved_bbt — [NAND Interface] check if a block is reserved 👑

like… that's it. that's the whole vibe. you point at a block, she tells you if it's reserved. no cap. 💅

✨ SYNOPSIS ✨

int nand_isreserved_bbt (struct nand_chip *this , loff_t offs );

look at her. returns an int, takes two args, done. main character energy fr fr 🦋

🫶 ARGUMENTS 🫶

  • this — the NAND chip object 🧚 like, the actual chip you're asking about. she needs to know who she's working with, obviously.
  • offs — offset in the device 📍 your little location pin inside the device. where in the NAND are we even talking about, bestie?
lowkey the whole function is just these two args and a vibe check on whether that block is reserved. short king behavior. 💜

💖 SEE ALSO 💖

okay this is where it gets good — the kernel file ./drivers/mtd/nand/raw/nand_bbt.c is absolutely stacked, like a full friend group of functions, and you should say hi to every single one of them 🫶✨

the way this list just keeps going 😭 it's giving "she has a lot of friends and they're all in nand_bbt.c" and honestly? we love that for her 🌈

and that's the page!! mwah 💋 this little icon lives in ./drivers/mtd/nand/raw, dated October 2026 — so go forth, check your reserved blocks, and slay 💅🎀🦋💖
