skb_fill_page_desc_noacc(9)

💖 NAME 💖

okay so bestie, welcome to skb_fill_page_desc_noacc(9) from the Kernel API Manual — it’s literally the function that initialises a paged fragment in an skb. 💅✨

✨ SYNOPSIS ✨

void skb_fill_page_desc_noacc (struct sk_buff *skb , int i , struct page
       *page , int off , int size );

🎀 ARGUMENTS 🎀

• skb — the buffer containing the fragment you’re initialising. It’s the main-character skb, obviously. 🫶
• i — the paged fragment index to initialise. Which slot are we filling? That one. ✨
• page — the page to use for this fragment. The page is the vibe. 🦋
• off — the offset to the data with page. Like, where the data sits in that page. 🎀
• size — the length of the data. How much data we’re talking about. 🌸

🦋 DESCRIPTION 🦋

This is the variant of skb_fill_page_desc that does not deal with pfmemalloc when the page is not owned by us. That’s the whole vibe: fragment-initialising energy, but no pfmemalloc handling when the page isn’t ours. 💅✨

fr fr, the “noacc” part is the key: it’s the variant that skips the pfmemalloc stuff when the page is not owned by us. 🫶
