skb_unlink(9)

🦋 skb_unlink(9) 🦋

okay so welcome to the Kernel API Manual, bestie — today's main character is skb_unlink(9), and she's serving “remove a buffer from a list” with full main-character energy. 💅✨

✨ NAME ✨

skb_unlink — remove a buffer from a list. that's the whole job, and she ate. 🎀

🎀 SYNOPSIS 🎀

void skb_unlink (struct sk_buff *skb , struct sk_buff_head *list );

🫶 ARGUMENTS 🫶

• skb — buffer to remove. literally the packet bb you're taking out of the list. 💖
• list — list to use. the queue that's holding your SKB, bestie. ✨

💅 DESCRIPTION 💅

so this function removes a packet from a list. the list locks are taken, and this function is atomic with respect to other list locked calls — no cap, that's the lock vibe. 🔥

you must know what list the SKB is on. like, actually know it. don't be out here guessing, bestie. 🫶
