report_dedupe_timeouts(9)

💖 report_dedupe_timeouts(9) 💖

okay so bestie, welcome to a little corner of the kernel API manual (section 9, we love her) — this one's all about telling the world that some dedupe requests just... never got an answer and had to be timed out. 😭

✨ NAME ✨

report_dedupe_timeouts — record (and eventually report) that some dedupe requests hit their expiration time without ever getting an answer, so we timed them out. 🕰️💀

🌸 SYNOPSIS 🌸

void report_dedupe_timeouts (struct hash_zones *zones , unsigned int timeouts );

🎀 ARGUMENTS 🎀

• zones — the hash zones. yep, that's them. the whole zone-y situation. 💅
• timeouts — the number of newly timed out requests. like, how many fresh victims we're reporting this round. 🔥
