look at her. she's iconic. copy her exactly, no cap:

    struct acrn_vm          *vm;
    struct list_head        list;
    bool is_default;
    unsigned long           flags;
    struct list_head        range_list;
    rwlock_t range_lock;
    unsigned long ioreqs_map[BITS_TO_LONGS( ACRN_IO_REQUEST_MAX)];

🌸 Members 🌸

okay now the main character energy part — every single field, explained by your girl 💅

• name — Client name. it's her name, bestie, she has one 🎀
• vm — The VM that the client belongs to. like, whose house is she in 🏠
• list — List node for this acrn_ioreq_client. the little link in the chain, iykyk 🔗
• is_default — If this client is the default one. lowkey the group-chat admin of clients 👑
• flags — Flags (ACRN_IOREQ_CLIENT_*). yes the asterisk is doing work, don't come for her ⭐
• range_list — I/O ranges. the whole map of where she's allowed to roam 🗺️
• range_lock — Lock to protect range_list. she guards the map, no cap, do NOT forget to take her first 🫶
• ioreqs_map — The pending I/O requests bitmap. the to-do list, the pile of unread messages, the whole mood 😭
• handler — I/O requests handler of this client. the one who actually does the work, ate and left no crumbs 🔥
• thread — The thread which executes the handler. the girl literally running the handler, main character fr 🧚
• wq — The wait queue for the handler thread parking. her little parking spot while she waits 💤
• priv — Data for the thread. the private stash, just for her, don't ask 🙈
