unregister_netdevice_queue(9)

okay so bestie, welcome to the Kernel API Manual entry for unregister_netdevice_queue(9) — manual name folded in right here at the top, cute and efficient, no boring header-line energy. 💅✨

💖 NAME 💖

unregister_netdevice_queue — remove device from the kernel. that’s the whole assignment, periodt. 👑

🎀 SYNOPSIS 🎀

here’s the signature, verbatim, no edits bestie: 🫶

void unregister_netdevice_queue (struct net_device *dev , struct
       list_head *head );

💬 ARGUMENTS 💬

• dev — device. literally the device, bestie. 🫶
• head — list. yep, the list. 💅

🌸 DESCRIPTION 🌸

okay so here’s the tea: this function shuts down a device interface and removes it from the kernel tables. ✨ no cap.

If head is not NULL, the device is queued to be unregistered later — like, later later, not right this second. ⏳

🚨 caveat bestie: callers must hold the rtnl semaphore. this is not a drill. 🔒

And if you’re over there wondering if this is the one you want: the page literally says you may want unregister_netdev instead of this. so maybe go peek at that one too, iykyk. 💅

mwah 💋 that’s the whole page. source/version: ./net/core; date: October 2026. now go hold that rtnl semaphore like the main character you are. 👑🌈
