🦋 sysfs_attr_init 🦋

okay so this is the sysfs_attr_init(9) page from the Kernel API Manual, and it's short but lowkey important, bestie. no cap.

✨ NAME ✨

sysfs_attr_init — initialize a dynamically allocated sysfs attribute. that's the whole vibe.

---

🌸 SYNOPSIS 🌸

sysfs_attr_init (attr );

---

🎀 ARGUMENTS 🎀

• attr — the struct attribute you're initializing. that's it. that's the argument. 💅

---

💖 DESCRIPTION 💖

okay so you use this to initialize a dynamically allocated struct attribute so we can make lockdep happy. yes, literally that's the goal: lockdep happiness. 🫶

this is a new requirement for attributes, and initially this is only needed when lockdep is enabled. so if lockdep is on, bestie, you gotta do this.

why? because lockdep gives a nice error when your attribute is added to sysfs if you don't have this. and not the cute kind of error. so initialize your dynamically allocated struct attribute and let lockdep live its best life. periodt. 🔥
