💖 ksmbd_init_rdma_sg(9) — Kernel API Manual, bestie edition 💖

okay so welcome to the <pink>Kernel API Manual</pink> page for ksmbd_init_rdma_sg(9), and no cap this one is literally about building an AEAD scatterlist for an RDMA payload 🌸.

🌸 NAME 🌸

ksmbd_init_rdma_sg — build an AEAD scatterlist for an RDMA payload, periodt 💅.

✨ SYNOPSIS ✨

       struct scatterlist * ksmbd_init_rdma_sg (void *buf , unsigned int buflen
       , u8 *tag , unsigned int taglen );

🫶 ARGUMENTS 🫶

• buf — the payload buffer, like the main character of your data 💖
• buflen — payload length, aka how much payload we're serving 🍓
• tag — authentication tag buffer, the lil tag bestie 🎀
• taglen — authentication tag length, fr fr 📏

💖 DESCRIPTION 💖

So the way this works: it splits <cyan>vmalloc-backed payloads</cyan> at page boundaries, then appends the detached authentication tag as the final scatterlist entry. That's the whole vibe, and it's giving exactly what it needs to give ✨.

🎀 RETURN 🎀

It returns the allocated scatterlist 💅, or NULL on allocation failure 😭. No cap, that's the whole return situation.
