void init_sgs_pages (struct scatterlist **sg , struct page **pages , int
       dpos , int dlen , u8 *pad );

🎀 ARGUMENTS 🎀

  • sg — the scatterlist to populate. yes bestie, this is the one you're filling in 💅
  • pages — pointer to the page array. the source material, fr fr 🦋
  • dpos — position in the array to start, in bytes ⭐
  • dlen — len to add to sg, in bytes 📏
  • pad — pointer to the pad destination, if there is one 🙈

💫 DESCRIPTION 💫

so here's the vibe: you populate the scatterlist from the page array, starting at an arbitrary byte in the array and running for a specified length. that's the whole assignment, no cap 💖
