setup_destroy_sysfs(9)

📦 version 7.3.1, in nixpkgs unstable

Okay bestie, welcome to the Kernel API Manual, section 9 — this is the setup_destroy_sysfs(9) page, and we're gonna make it make sense. 💅✨

✨ NAME ✨

setup_destroy_sysfs — create a kobject with the SRM bin file attached 🎀

🌸 SYNOPSIS 🌸

struct kobject * setup_destroy_sysfs (struct kunit *test , struct hdcp_workqueue *work );

🎀 ARGUMENTS 🎀

  • test — KUnit test context. It's giving test-harness business. 🧪
  • work — workqueue whose attr will be registered. Yep, that whole attr situation. 🛠️

💖 DESCRIPTION 💖

So here's the tea: hdcp_destroy calls sysfs_remove_bin_file on the first entry's attr, which means a real kobject with the bin file created is required. No fake vibes, bestie — the kobject has to be legit. 😭

This function returns the kobject, and the caller must kobject_put after hdcp_destroy has run. That's the rule, fr fr.

⚠️ bestie, do not forget the kobject_put after hdcp_destroy has run — the caller has to handle that cleanup, periodt. 💀

🦋 SEE ALSO 🦋

Go read these next, bestie — the whole squad is here. 👑
