binder_proc_lock(9)

💅 binder_proc_lock(9) — the Kernel API Manual glow-up ✨

okay so real talk, bestie: this is a page from the Kernel API Manual and it's about binder_proc_lock. she's a tiny function with big "locks the outer door so nobody trashes the place" energy, and honestly? iconic. let's get into it 🎀

---

✨ NAME ✨

binder_proc_lock — acquire the outer lock for a given binder_proc 🔒

---

🌸 SYNOPSIS 🌸

binder_proc_lock (proc );

that's it. that's the whole call. no cap. 🫶

---

🦋 ARGUMENTS 🦋

• proc — the struct binder_proc you're trying to acquire, like the main character she is 👑

---

💖 DESCRIPTION 💖

okay so what she does: binder_proc_lock acquires proc->outer_lock. that's the vibe. ✨

and what's that lock even for? it's used to protect the binder_ref structures associated with the given proc. so like, the binder_ref stuff hanging out with proc? that's the outer lock's whole job to keep safe. periodt. 💅

ngl if you're in binder land you're gonna see outer_lock everywhere — she's the outer one, meaning she's the first lock you grab, and there's a whole inner/outer naming thing going on (see the many friends below, iykyk). 🧚

💀 quick heads-up babe: a bunch of those names end in _olocked and _ilocked, which is giving "outer-locked" and "inner-locked" — so like, know which lock you're holding before you call them, mwah. 😘
