✨ sysfs_bin_attr_init(9) ✨

okay bestie, welcome to the Kernel API Manual 💖 this one's a lil cutie from the sysfs corner of the kernel, so grab ur matcha and let's go 🍓

---

🌸 NAME 🌸

sysfs_bin_attr_init — it literally initializes a dynamically allocated bin_attribute 👑 that's it, that's the whole job, and she does it well periodt

---

🦋 SYNOPSIS 🦋

sysfs_bin_attr_init (bin_attr );

---

🎀 ARGUMENTS 🎀

• bin_attr — ngl the original docs just say -- undescribed -- 😭 so like... it's the bin_attribute you're initializing, obviously, but the manpage itself gives us nothing more than that. no cap, that's all she wrote 💀

---

💅 DESCRIPTION 💅

so basically you call sysfs_bin_attr_init to initialize a dynamically allocated struct bin_attribute — and the whole reason it exists is to make lockdep happy 🫶 like, lockdep is that friend who needs everything just so, and this function is how you keep her chill.

this is a new requirement for attributes, okay? and initially it's only needed when lockdep is enabled 🔥

and here's the tea: if you don't have this, lockdep will give you a nice error when your attribute gets added to sysfs 😭 so like... do the thing, bestie. call the function. keep lockdep happy. it's giving self-care honestly ✨

🫶 friendly reminder that this is a requirement now — skipping it is how you end up with a lockdep complaint on your timeline and nobody wants that 🙈
