get_hash_zone_statistics(9)

💖 get_hash_zone_statistics(9) — the bestie edition 💖

okay so real talk, this one lives in the Kernel API Manual, and it's genuinely one of the shorter ones, so grab a boba and let's go 🧋✨

✨ NAME ✨

get_hash_zone_statistics — literally just adds the statistics for this hash zone to the tally for all zones. that's it. that's the whole job. she's a team player, she's folding her numbers into the group chat total 🫶

🌸 SYNOPSIS 🌸

void get_hash_zone_statistics (const struct hash_zone *zone , struct hash_lock_statistics *tally );

🎀 ARGUMENTS 🎀

• zone — the hash zone to query. this is the girl you're asking for her receipts 💅
• tally — the tally. yeah. that's the whole description. the tally. the running total. the collective pot. iconic brevity, no notes 👑
