DEVICE_ATTR_RW_NAMED(9)

💖 DEVICE_ATTR_RW_NAMED 💖

okay bestie, so this one lives in the Kernel API Manual and it's genuinely so cute — it's the macro that lets you make a read-write device attribute whose sysfs name is not the same as the function name. like, the glow-up where the vibe check name and the government name are two different things 🦋

---

✨ NAME ✨

DEVICE_ATTR_RW_NAMED — define a read-write device attribute where the sysfs name is lowkey different from the function name. that's the whole thing, no cap 💅

---

🌸 SYNOPSIS 🌸

DEVICE_ATTR_RW_NAMED (_name , _attrname );

---

🎀 ARGUMENTS 🎀

• _name — the attribute function preface, aka the little name-bit that goes on the function side of things 🫶
• _attrname — the attribute name as it wil be exposed in the sysfs. this is the name the world actually sees, so pick a good one ✨

---

💜 DESCRIPTION 💜

so it's literally like DEVICE_ATTR_RW, bestie — same energy, same read-write slay — except it also lets you reuse names under separate paths in the same driver. iconic behaviour honestly 👑

like yes you're reusing the name, but it's fine because the paths are different. it's giving "same name, different context," and it works 🔥
