start_updating(9) 💅

okay so this page is from the Kernel API Manual — manual-name drop, folded in near the top like a lil name tag, no cap. It’s all about one function and it’s giving dedupe endgame energy. 🦋

🌸 NAME 🌸

start_updating — continue deduplication with the last step, updating UDS with the location of the duplicate that should be returned as advice in the future. 💖

void start_updating (struct hash_lock *lock , struct data_vio *agent );

it’s a void function, bestie — literally no return value comes back out. The signature is right there, character for character. ✨

🎀 ARGUMENTS 🎀

• lock — the hash lock. periodt.
• agent — the data_vio currently acting as the agent for the lock. That’s the one on duty rn, main character energy. 👑
