nanddev_target_size(9)

💅 nanddev_target_size — bestie's guide to the Kernel API Manual ✨

okay so like, the manual we're living in is the Kernel API Manual, and today's main character is a little function called nanddev_target_size. she's short, she's sweet, she tells you how much space one single target/die gives you. that's it. that's the whole vibe. let's get into it 🎀

---

✨ NAME ✨

nanddev_target_size — get the total size provided by a single target/die 🦋

like, one die. one target. how many bytes is she serving. that's the question.

---

🌸 SYNOPSIS 🌸

u64 nanddev_target_size (const struct nand_device *nand );

that's the whole signature bestie, she takes exactly one thing and returns a u64. no cap. 💜

---

🫶 ARGUMENTS 🫶

• nand — the NAND device. yes that's it. that's the parameter. she just wants the device, she handles the rest 👑

---

⭐ RETURN ⭐

the total size exposed by a single target/die in bytes. so like, a number. a u64 number. in BYTES, don't forget the units, that's how they get you 😭

🌈 SEE ALSO 🌈

okay this section is giving extended universe and honestly? iconic. the whole NAND lore drops here, starting with the actual kernel file:

Kernel file ./include/linux/mtd/nand.h struct

then the whole friend group, no one left out, fr fr:

like I said. the whole extended universe. go read them, iykyk 💀

ngl this page is short but she ate. one arg, one return, one very long SEE ALSO list. main character energy tbh 💅

and that's the tea bestie 🍓 — this serves you from ./include/linux/mtd, dated October 2026, and the page itself is nanddev_target_size(9) in the Kernel API Manual. mwah, go forth and size those targets 💖✨
