sg_init_table(9)

🎀 NAME 🎀

sg_init_table — Initialize SG table

okay bestie, welcome to sg_init_table(9) from the Kernel API Manual ✨ this is the page where we initialize an SG table, and it’s giving kernel-core main character energy, no cap 💅

🌸 SYNOPSIS 🌸

void sg_init_table (struct scatterlist *sgl , unsigned int nents );

💖 ARGUMENTS 💖

• sgl — The SG table. literally the table itself, bestie 🫶
• nents — Number of entries in table. yes ma’am, the count of entries, fr fr ✨

🚨 NOTES 🚨

okay important note, bestie: If this is part of a chained sg table, sg_mark_end should be used only on the last table part. so like… only the last table part gets that treatment, periodt 💅
