💅 nand_region_is_secured(9) 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — yes, that section 9, the kernel one, not the "read the fine print" one 😭 this is the page for nand_region_is_secured, and honestly? it's a little baddie with one job and it does it slayfully 💖

✨ NAME ✨

nand_region_is_secured — literally just checks if a region is secured 🎀 that's it, that's the whole vibe check

🦋 SYNOPSIS 🦋

bool nand_region_is_secured (struct nand_chip *chip , loff_t offset ,
u64 size );

look at her go. returns a bool, takes three args, no cap 💅

🌸 ARGUMENTS 🌸

  • chip — the NAND chip object 🧚 like, the actual chip you're asking about
  • offset — offset of the region you wanna check 📍
  • size — size of the region you wanna check 📏

💜 DESCRIPTION 💜

so what does she do? she checks if the region is secured by comparing the offset and size you handed her against the list of secure regions obtained from DT 👑 (device tree, iykyk).

returns true if the region is secured 💖 else false 🫶

that's the whole flow. no drama, no side quests, just a clean little comparison and a boolean. iconic behavior honestly ✨

🔥 SEE ALSO 🔥

the girlies she hangs out with 💅 all of these are from the kernel file ./drivers/mtd/nand/raw/nand_base.c — go say hi:

💀 real talk: this page lives in ./drivers/mtd/nand/raw — that's the source path, that's her address, don't @ me.

okay that's the whole page bestie, go forth and check your regions 🦋✨💖
