🌸 skb_queue_purge_reason(9) — the Kernel API Manual, bestie edition 🌸

okay so this one lives in the Kernel API Manual, section 9, and the function is literally called skb_queue_purge_reason 💅 yes the name is a lot. it's fine. she's iconic.

✨ NAME ✨

skb_queue_purge_reason — empty a list 🗑️✨

🎀 SYNOPSIS 🎀

void skb_queue_purge_reason (struct sk_buff_head *list , enum
       skb_drop_reason reason );

that's it. that's the whole signature. no cap. 🫶

💖 ARGUMENTS 💖

  • list — the list you wanna empty, bestie. that's the vibe. 🌸
  • reason — the drop reason 👀 like, why are we dropping these. you gotta say.

🦋 DESCRIPTION 🦋

okay so picture this: you've got an sk_buff list and it's FULL. and you're like "not me having all these buffers". so you call this. it deletes all the buffers on an sk_buff list 🧹✨

the way it works: each buffer is removed from the list, and one reference is dropped for each one. one per buffer. that's the deal. 💀

and here's the part that lowkey matters — this function takes the list lock, which means it's atomic with respect to other list locking functions 🔒 like, nobody else can sneak in and mess with the list while she's doing her thing. main character energy fr fr. 👑

no cap, that locking detail is the whole point, don't skip it 🫶

🌈 SEE ALSO 🌈

okay this list is LONG long, but it's giving "she knows everyone at the party", so here we go 👑 all of these are in the kernel file ./net/core/skbuff.c:

like I said. everyone. 🫶✨

and that's the page!! 💜 this one came from ./net/core and it's dated October 2026 — so yeah, mark your calendar bestie, she's a fall girlie 🍓🎀

mwah, go empty that list 💅✨
