aggr_cpu_id__node(9)

🌸 NAME 🌸

okay so this is aggr_cpu_id__node(9), straight outta the Kernel API Manual, and bestie it does exactly one iconic thing: it creates an aggr_cpu_id with the numa node populated for cpu. The function signature is compatible with aggr_cpu_id_get_t. that's the whole vibe. 💅

✨ SYNOPSIS ✨

struct aggr_cpu_id aggr_cpu_id__node (struct perf_cpu cpu , void *data
       );

look at her. copy it exactly, no cap. 🫶

🎀 ARGUMENTS 🎀

• cpu — the page says -- undescribed --, so that's literally all we get. 🙈
• data — same deal: -- undescribed --. the manual left this one blank too. 😭

no invented lore here, bestie — just the facts as printed.
