nand_sync(9)

💅 nand_sync(9) — the kernel API manual, but make it make sense 🎀

okay so bestie, we're in section 9 of the Kernel API Manual, and today's main character is nand_sync. it lives in ./drivers/mtd/nand/raw/nand_base.c, it's part of the [MTD Interface], and honestly? it's a vibe. let's get into it ✨

---

🌸 NAME 🌸

nand_sync — the [MTD Interface] sync. that's it, that's the name, and she's serving exactly what the label says 💅

---

🦋 SYNOPSIS 🦋

void nand_sync (struct mtd_info *mtd );

no return value, one argument, zero drama. she takes her pointer and she goes 😌

---

💖 ARGUMENTS 💖

• mtd — the MTD device structure. like, the actual MTD device. hand it your struct mtd_info * and you're genuinely set 🫶

---

✨ DESCRIPTION ✨

okay so here's the tea 🔥 "sync" sounds all fancy and synchronization-y, right? nope. bestie, sync here is actually just a wait for chip ready function. that's the whole personality. it waits for the chip to be ready. no cap. it's giving "the function name is aspirational, the function body is a vibe check" 😭
