erased_sector_bitflips(9)

💅 erased_sector_bitflips(9) — Kernel API Manual bestie era ✨

🌸 NAME 🌸

erased_sector_bitflips — count bit flips. That's the name, that's the job, periodt. 💖

🦋 SYNOPSIS 🦋

okay so the signature is literally this, bestie — no cap:

       int erased_sector_bitflips (u_char *data , u_char *oob , struct
       omap_nand_info *info );

🎀 ARGUMENTS 🎀

• data — data sector buffer. highkey main character energy, fr fr. 💅
• oob — oob buffer. lowkey the sidekick, but iconic. 🫶
• info — omap_nand_info. yep, that's the struct. ✨

🔥 DESCRIPTION 🔥

Okay so here's the vibe check: it checks whether the bit flips in an erased page fall below the correctable level. If they do fall below, it reports the page as erased with correctable bit flip. If they don't, it reports it as uncorrectable page. That's the whole plot — slay. 💀
