ENUM NAND_PAGE_IO_REQ_TYPE(9)

💅 enum nand_page_io_req_type(9) — the Kernel API Manual, bestie edition

okay so this is a page from the Kernel API Manual (that's the enum nand_page_io_req_type(9) manual, iykyk) and it's genuinely so simple it's iconic.

✨ NAME ✨

enum nand_page_io_req_type — literally just the Direction of an I/O request. which way is the data going?? that's it. that's the whole vibe check. 🦋

---

🌸 SYNOPSIS 🌸

enum nand_page_io_req_type {
    NAND_PAGE_READ ,
    NAND_PAGE_WRITE

};

look at her. two constants. no notes. periodt. 💅

---

🎀 Constants 🎀

• NAND_PAGE_READ — data flowing from the chip, to the controller. the chip is doing the talking, the controller is listening. main character energy tbh. 👑
• NAND_PAGE_WRITE — data flowing from the controller, to the chip. now the controller's in charge and the chip is receiving. roles reversed, slay. ✨

ngl bestie, this enum is the entire personality of the direction of an I/O request — nothing more, nothing less. no cap. 💯

okay that's the whole page, you ate that 💖 this lil gem lives in ./include/linux/mtd and the manual's dated October 2026, closing out as enum nand_page_io_req_type(9) — mwah, goodbye bestie! 🌈⭐🍓
