✨ NAME ✨

okay bestie, welcome to the struct zfcp_diag_adapter(9) page from the Kernel API Manual 💖 struct zfcp_diag_adapter — central storage for all diagnostics concerning an adapter. literally the main-character closet where all the adapter diagnostic fits get kept 👑

🦋 SYNOPSIS 🦋

       struct zfcp_diag_adapter {
           unsigned long   max_age;
           struct zfcp_diag_adapter_port_data {
             struct zfcp_diag_header         header;
             struct fsf_qtcb_bottom_port     data;
           } port_data;
           struct zfcp_diag_adapter_config_data {
             struct zfcp_diag_header         header;
             struct fsf_qtcb_bottom_config   data;
           } config_data;
        };
