onenand_block_isbad_nolock(9)

🌸 NAME 🌸

okay bestie, welcome to the onenand_block_isbad_nolock(9) page from the Kernel API Manual. The function is onenand_block_isbad_nolock and its whole name-tag is [GENERIC] Check if a block is marked bad. no cap, that's the vibe 💅

✨ SYNOPSIS ✨

int onenand_block_isbad_nolock (struct mtd_info *mtd , loff_t ofs , int allowbbt );

🎀 ARGUMENTS 🎀

• mtd — MTD device structure. this is the device info bestie 🫶
• ofs — offset from device start. literally where you're looking 👀
• allowbbt — 1, if it's allowed to access the bbt area. yes, that's the whole description 💀

💖 DESCRIPTION 💖

Check if the block is bad, bestie. It does this either by reading the bad block table or by calling the scan function. those are the two paths, and that's it—no extra lore 😭✨
