locks_translate_pid(9)

💅 locks_translate_pid(9) — from the Kernel API Manual, bestie ✨

okay so picture this: you're deep in the kernel, and somebody hands you a file_lock and is like "hey what's the pid on this thing" — but plot twist, a pid is only meaningful inside a namespace, so you can't just raw-dog it. that's literally this function's whole job. translating a fl_pid into a namespace virtual pid number. it's giving passport control for process IDs 🛂✨

✨ NAME ✨

locks_translate_pid — the glow-up translator that turns a file_lock's fl_pid number into a namespace 🦋

---

🎀 SYNOPSIS 🎀

pid_t locks_translate_pid (struct file_lock_core *fl , struct pid_namespace *ns );

---

🌸 ARGUMENTS 🌸

• fl — the file_lock whose fl_pid is the one getting translated, bestie. this is your main character 🫶
• ns — the namespace you want that pid translated into. the destination vibe check 💫

---

💖 DESCRIPTION 💖

So basically: this is the function you call to translate a fl_pid into a namespace virtual pid number. that's it, that's the tea ☕ no cap, that's the whole description — no secret bonus features, no hidden drama. it's a translator, not a magician 🧚💜
