STRUCT HL_SYNC_TO_ENGINE_MAP(9)

🦋 struct hl_sync_to_engine_map(9) — Kernel API Manual 🦋

okay so bestie, welcome to the Kernel API Manual corner where the main character is struct hl_sync_to_engine_map. it's giving tiny struct, huge mapping energy, and we're gonna get into it.

✨ NAME ✨

struct hl_sync_to_engine_map — maps a sync object id to the associated engine id. literally matchmaker behaviour, but for ids. 💅

🌸 SYNOPSIS 🌸

the struct is serving:

       struct hl_sync_to_engine_map {
           unsigned long tb[1 << (( SYNC_TO_ENGINE_HASH_TABLE_BITS) - 1)];
        };

💅 Members 💅

• tb — the hash table containing the mapping; each element is of type struct hl_sync_to_engine_map_entry. that's the whole tea, no cap. 🫶
