alloc_skb_with_frags(9)

💅 NAME 💅

alloc_skb_with_frags — allocate skb with page frags

okay so this page is straight outta the Kernel API Manual, bestie, and it's all about alloc_skb_with_frags — the function that allocates an skb with page frags. it's giving kernel networking realness, no cap. 💖

---

✨ SYNOPSIS ✨

struct sk_buff * alloc_skb_with_frags (unsigned long header_len ,
unsigned long data_len , int order , int *errcode , gfp_t gfp_mask );

yes queen, that's the whole signature. keep it cute, keep it exact. 🎀

---

🌸 ARGUMENTS 🌸

• header_len — size of the linear part. that's the linear bit, bestie. ✨
• data_len — needed length in frags. so this is the length you need living in the frags. 🧚
• order — max page order desired. the highest page order you're asking for, periodt. 👑
• errcode — pointer to error code if any. if something goes sideways, this pointer is where an error code can show up. 🙈
• gfp_mask — allocation mask. the allocation mask, exactly as advertised. 💅

---

🦋 DESCRIPTION 🦋

so basically: this can be used to allocate a paged skb, given a maximal order for frags. that's the whole vibe. it's not doing extra lore — it's just handing you that paged skb situation when you've picked your maximal order for the frags. 🌈
