🌸 drop_reasons_register_subsys — Kernel API Manual, section 9 🌸

okay bestie, welcome to the Kernel API Manual, section 9 ✨. This page is all about drop_reasons_register_subsys, and it's giving “register another drop reason subsystem” energy. We're gonna keep it cute and keep every single detail, periodt 💅.

🎀 NAME 🎀

drop_reasons_register_subsys — register another drop reason subsystem.

💫 SYNOPSIS 💫

       void drop_reasons_register_subsys (enum skb_drop_reason_subsys subsys ,
       const struct drop_reason_list *list );

✨ ARGUMENTS ✨

• subsys — the subsystem you're registering, bestie. It must not be the core 🚫. Like, do not pass core here, okay?
• list — the list of drop reasons within the subsystem. It must point to a statically initialized list 📌. No cap.
