STRUCT NAND_OPERATION(9)

🎀 struct nand_operation(9) — NAND operation descriptor 🎀

Okay bestie, welcome to the struct nand_operation(9) page in the Kernel API Manual. We’re doing the NAND operation descriptor today, and it’s lowkey iconic ✨.

💖 NAME 💖

struct nand_operation — NAND operation descriptor. That’s the whole name-and-one-liner situation 🫶.

🦋 SYNOPSIS 🦋

Here’s the shape of the struct, no cap:

struct nand_operation {
    unsigned int cs;
    bool deassert_wp;
    const struct nand_op_instr *instrs;
    unsigned int ninstrs;
 };

🌸 Members 🌸

• cs — the CS line to select for this NAND operation.
• deassert_wp — set to true when the operation requires the WP pin to be de-asserted (ERASE, PROG, ...).
• instrs — array of instructions to execute.
• ninstrs — length of the instrs array.

🌈 Description 🌈

This is the actual operation structure that will be passed to chip->exec_op. That’s the tea ☕ — it’s the real descriptor doing the rounds.

Okay bye bestie! The footer source/version line was ./include/linux/mtd, and the date on it is October 2026. Go read some kernel headers, slay 💅💜.
