trim_sg_list(9)

✨ NAME ✨

okay so we're deep in the Kernel API Manual and today's page is trim_sg_list(9) 💖. The function is trim_sg_list — ensures the bound in sg list. That's the vibe, that's the job, periodt 👑.

🌸 SYNOPSIS 🌸

long int trim_sg_list (struct nx_sg *sg , struct nx_sg *end , unsigned
       int delta , unsigned int *nbytes );

💅 ARGUMENTS 💅

• sg — sg list head. It's literally the head of the sg list, main character energy 👑.
• end — sg lisg end. Yes bestie, the page says sg lisg end, and we are preserving that spelling exactly, no cap 💀.
• delta — is the amount we need to crop in order to bound the list. This is the crop amount, the little trim that keeps the list bounded ✂️.
• nbytes — length of data in the scatterlists or data length - whichever is greater. Keep that comparison in mind: whichever is greater, bestie 🫶.
