STRUCT BATADV_WIFI_NET_DEVICE_STATE(9)

💖 struct batadv_wifi_net_device_state(9) — Kernel API Manual 💖

okay so bestie, welcome to the Kernel API Manual page for struct batadv_wifi_net_device_state(9) — it’s giving “little cache with main character energy” and I’m obsessed. We’re keeping every field, every reference, and every crumb of info, periodt 💅

✨ NAME ✨

struct batadv_wifi_net_device_state — cache of wifi information of net_devices. literally that’s the whole name, no cap 🎀

🎀 SYNOPSIS 🎀

Here’s the struct in all its exact, copy-pasteable glory:

struct batadv_wifi_net_device_state {
    struct rhash_head l;
    struct net_device *netdev;
    netdevice_tracker dev_tracker;
    u32 wifi_flags;
    struct rcu_head rcu;
 };

🦋 Members 🦋

okay so every field is here, doing its thing:

• l — anchor in rhashtable — yes, the anchor, keeping it anchored 💅
• netdev — pointer to the net_device — it’s literally pointing at the net_device, slay 🫶
• dev_tracker — device tracker for netdev — tracker behavior, we love to see it 🎀
• wifi_flags — flags whether this is (directly or indirectly) a wifi interface — direct or indirect, it’s flagging the wifi situation ✨
• rcu — struct used for freeing in an RCU-safe manner — RCU-safe freeing, no chaos allowed 😭
