skb_pfmemalloc(9)

🌸 NAME 🌸

okay bestie, this is the skb_pfmemalloc(9) page from the Kernel API Manual — the function that tests if the skb was allocated from PFMEMALLOC reserves. that's literally the whole vibe: “was this skb living in PFMEMALLOC reserves?” 👀✨

✨ SYNOPSIS ✨

signature, exactly as it is, no edits, periodt:

bool skb_pfmemalloc (const struct sk_buff *skb );

🎀 ARGUMENTS 🎀

• skb — buffer. that's the buffer you're checking, bestie 🫶
