vdo_get_dedupe_statistics(9)

🎀 NAME 🎀

Okay bestie, welcome to the vdo_get_dedupe_statistics(9) page from the Kernel API Manual — yes, that manual. This function is here to tally the statistics from all the hash zones and the UDS index. That's it, that's the job, and it's lowkey iconic. ✨

💅 SYNOPSIS 💅

       void vdo_get_dedupe_statistics (struct hash_zones *zones , struct
       vdo_statistics *stats );

💖 ARGUMENTS 💖

• zones — the hash zones you're querying. Gotta know which zones, bestie. 🎯
• stats — a structure where the statistics get stored. That's the drop spot. 📥

🔥 RETURN 🔥

The RETURN section is literally giving the sum of the hash lock statistics from all hash zones plus the statistics from the UDS index. Math girl summer, no cap. 🧮💖
