assert_hash_lock_agent(9)

💅 assert_hash_lock_agent(9) 💅

okay so welcome to the Kernel API Manual page for assert_hash_lock_agent(9), bestie. this is the little assertion helper that checks a data_vio is the agent of its hash lock, and that this is being called in the hash zone. no cap, it's giving "trust but verify" energy. ✨

---

🌸 NAME 🌸

assert_hash_lock_agent — assert that a data_vio is the agent of its hash lock, and that this is being called in the hash zone. 💖

the way that this is literally a vibe check for lock-agent-ness, iykyk. 🫶

---

✨ SYNOPSIS ✨

here's the signature, exactly as it appears — don't freestyle it, bestie:

void assert_hash_lock_agent (struct data_vio *data_vio , const char
       *where );

---

🎀 ARGUMENTS 🎀

• data_vio — the data_vio that is expected to be the lock agent. this is the main character we're checking, okay? 👑
• where — a string that describes the function making the assertion. it's literally the "who is calling" receipt. 🧾
