STRUCT REQUEST_TRACKER(9)

🎀 NAME 🎀

okay so bestie, this is struct request_tracker from the Kernel API Manual — struct request_tracker(9) — and it's literally the firmware request tracker. that's the whole name moment, no cap. 💅✨

🌸 SYNOPSIS 🌸

here's the struct exactly, indentation and all, because we do not play with code:

       struct request_tracker {
           u16 smid;
           u8 cb_idx;
           struct list_head tracker_list;
        };

🫶 Members 🫶

the member lineup is giving main character energy:

• smid — system message id. the id, periodt. 📬
• cb_idx — callback index. slay. 🎯
• tracker_list — list of free request (ioc->free_list). iconic. 🦋
