okay so bestie, welcome to the Kernel API Manual page for kernfs_get_active(9) — yes the manual name is literally that, iykyk, and we're getting into it 🫶

✨ NAME ✨

kernfs_get_active — get an active reference to kernfs_node 🌸

🦋 SYNOPSIS 🦋

struct kernfs_node * kernfs_get_active (struct kernfs_node *kn );

like, that's the whole vibe. short and iconic, no cap 👑

🎀 ARGUMENTS 🎀

  • kn — the kernfs_node you want to get an active reference to. that's it. that's the arg 💅

💜 DESCRIPTION 💜

so basically you call this to get an active reference of kn. that's the main character move ✨

and here's the slay detail: this function is noop if kn is NULL. so if kn is NULL, nothing happens at all — it just... vibes. doesn't crash, doesn't complain, literally noop 🧚 lowkey the most chill behaviour ever.
