💅 batadv_hard_if_event(9) — like, the kernel API manual bestie ✨

okay so real talk, you're reading the Kernel API Manual page for batadv_hard_if_event, and honestly? she's giving "quiet but crucial". let's get into it 🎀

🌸 NAME

batadv_hard_if_event — the netdevice notifier callback for hard interfaces, periodt.

✨ SYNOPSIS

int batadv_hard_if_event (struct notifier_block *this , unsigned long
event , void *ptr );

🫶 ARGUMENTS

  • this — the notifier block. lowkey she's just there vibing, literally unused 💀
  • event — the NETDEV_* event we're handling. main character energy, this is the actual occasion.
  • ptr — notifier info, pointing right at the affected net_device. she knows exactly which interface we're talking about 👑

🦋 DESCRIPTION

So here's the vibe: this function dispatches netdevice events that affect potential or existing hard interfaces. that's it, that's the job 💖

but bestie, important note — mesh interfaces are handled separately, by batadv_hard_if_event_meshif. don't come for her, they're different departments, iykyk. 🌈

⭐ RETURN

NOTIFY_DONE — and that's on doing your part and handing the notification chain back politely 🫡

no cap, it just returns NOTIFY_DONE, no drama, no complications. we love a low-maintenance return value 🙈
