__vdso_fute...2_try_unlock(9)

✨ NAME ✨

Okay so bestie, we're looking at __vdso_futex_robust_list32_try_unlock(9) from the Kernel API Manual 🫶 — and its whole mission is to try to unlock an uncontended robust futex with a 32-bit pending op pointer. Lowkey iconic, highkey niche 💅

---

🌸 SYNOPSIS 🌸

__u32 __vdso_futex_robust_list32_try_unlock (__u32 *lock , __u32 tid ,
       __u32 *pop );

---

🎀 ARGUMENTS 🎀

• lock — pointer to the futex lock object. Like, the lock itself, bestie 🔒
• tid — the TID of the calling task. That's the task's whole identifier vibe ✨
• pop — pointer to the task's robust_list_head::list_pending_op. Yes, that exact path, no cap 🧚

---

⭐ RETURN ⭐

It gives you back the content of *lock. And on success, that content is the same as tid — slay, matching values, we love to see it 💖

---

🦋 DESCRIPTION 🦋

Same as __vdso_futex_robust_list64_try_unlock, just with a 32-bit pop pointer. That's the tea ☕ — the 32-bit pop pointer is the whole difference here, periodt.
