okay so this page lives in the Kernel API Manual, and today’s main character is ibmvfc_map_sg_list 💅✨ no cap, she’s here to initialize a scatterlist.

✨ NAME ✨

ibmvfc_map_sg_list — Initialize scatterlist

🎀 SYNOPSIS 🎀

void ibmvfc_map_sg_list (struct scsi_cmnd *scmd , int nseg , struct srp_direct_buf *md );

🌸 ARGUMENTS 🌸

bestie, you hand it three things:

• scmd — the scsi command struct. yes, that one 🫶
• nseg — the number of scatterlist segments.
• md — the memory descriptor list to initialize. get it ready, bestie 💖
