DEVICE_ATTR_ADMIN_RW(9)

💅 DEVICE_ATTR_ADMIN_RW 💅

okay so bestie, welcome to the Kernel API Manual — this one's a tiny little macro page but it's lowkey iconic, and honestly it's giving "small but powerful" main character energy ✨

---

🌸 NAME 🌸

DEVICE_ATTR_ADMIN_RW — Define an admin-only read-write device attribute. 🎀

---

✨ SYNOPSIS ✨

DEVICE_ATTR_ADMIN_RW (_name );

---

🦋 ARGUMENTS 🦋

• _name — the attribute name. that's it. that's the whole vibe check. 👑

---

💖 DESCRIPTION 💖

So basically, this macro is exactly like DEVICE_ATTR_RW, no cap — except _mode is 0600. 🫶

ngl that 0600 is the whole point, girlies — it's admin-only, meaning the file perms lock everyone else out. that's the flex. 💅
