alloc_skb_fclone(9)

💖 alloc_skb_fclone(9) 💖

okay so this is the Kernel API Manual entry for alloc_skb_fclone, and we’re folding that manual-name moment right in at the top because we have things to do and buffers to allocate, bestie 🫶.

---

✨ NAME ✨

alloc_skb_fclone — allocate a network buffer from fclone cache 🌈

---

💅 SYNOPSIS 💅

struct sk_buff * alloc_skb_fclone (unsigned int size , gfp_t priority );

---

🎀 ARGUMENTS 🎀

• size — size to allocate 🍓
• priority — allocation mask 🎀

---

🦋 DESCRIPTION 🦋

okay so real talk: this function is a convenient wrapper around __alloc_skb. That’s the whole tea ☕ — it’s giving shortcut energy, and it allocates a network buffer from the fclone cache (NAME said it first, not me 💅).
