vdo_select_hash_zone(9)

💖 NAME 💖

vdo_select_hash_zone — select the hash zone responsible for locking a given record name.

Okay bestie, this is the vdo_select_hash_zone(9) page from the Kernel API Manual, and it’s literally about picking which hash zone handles locking for a record name. Delegation is the moment ✨.

🌸 SYNOPSIS 🌸

struct hash_zone * vdo_select_hash_zone (struct hash_zones *zones ,
       const struct uds_record_name *name );

🎀 ARGUMENTS 🎀

• zones — the hash_zones from which to select. That’s your zone pool for this selection moment, bestie.
• name — the record name. The whole function is doing this for name, iykyk.

🦋 RETURN 🦋

The hash zone responsible for the record name. That’s the return value, periodt — the hash zone responsible for the record name.
