skb_try_coalesce(9)

💖 NAME 💖

okay bestie, welcome to skb_try_coalesce(9) — straight outta the Kernel API Manual ✨. This function’s whole personality is: try to merge skb to prior one. That’s the mission. No cap. 🫶

✨ SYNOPSIS ✨

The signature, copied exactly so nobody comes for me:

bool skb_try_coalesce (struct sk_buff *to , struct sk_buff *from , bool
       *fragstolen , int *delta_truesize );

🎀 ARGUMENTS 🎀

Okay so the cast of characters is small but important:

• to — prior buffer. The one that was already there, bestie. 👑
• from — buffer to add. The new kid being considered for the merge. 🌱
• fragstolen — pointer to boolean. That’s it. That’s the description. 🎯
• delta_truesize — how much more was allocated than was requested. The overshoot receipt, basically. 🧾
