device_remove_file_self(9)

💅 device_remove_file_self(9) — the girlies' guide to the Kernel API Manual ✨

okay so bestie, we're in the Kernel API Manual today and this one is lowkey a little diva. sit down, grab a strawberry drink 🍓, and let's get into it.

---

🌸 NAME 🌸

device_remove_file_self — literally removes a sysfs attribute file from its own method. yes. from inside itself. it's giving main character energy, it's giving "i'll see myself out" 💅

---

✨ SYNOPSIS ✨

bool device_remove_file_self (struct device *dev , const struct device_attribute *attr );

that's the whole vibe. returns a bool, takes two things, we move.

---

🎀 ARGUMENTS 🎀

• dev — the device. like, the actual device device. 🫶
• attr — the device attribute descriptor. the little descriptor bestie that says what this attribute is.

---

🦋 DESCRIPTION 🦋

so what does it do? honestly the manpage is being mysterious and simply says: see kernfs_remove_self for details. that's it. that's the tea. no cap, that's the entire description — go read kernfs_remove_self(9) if you want the lore 🔥

like… that's the whole friend group, and every single one of them got an invite 💖

ngl the general device_remove_file(9) is right there in the list too, so if you're not doing the "remove myself from my own method" bit, maybe go say hi to that one first 🧚
