svc_rdma_xb_count_sges(9)

💖 NAME 💖

Okay so bestie, meet svc_rdma_xb_count_sges(9) — straight out of the Kernel API Manual and here to do exactly one iconic thing: Count how many SGEs will be needed ✨. That's it. That's the whole job. It's giving “one tiny but essential task” and honestly? Obsessed 💅.

✨ SYNOPSIS ✨

int svc_rdma_xb_count_sges (const struct xdr_buf *xdr , void *data );

🎀 ARGUMENTS 🎀

• xdr — an xdr_buf containing a portion of an RPC message to transmit. Lowkey the cargo being counted, no cap 🦋.
• data — pointer to arguments. Yes bestie, that's the whole description; it's short and it knows it 💖.

🔥 RETURN 🔥

Number of SGEs needed to Send the contents of xdr inline 🌈. That's the return value, periodt. No extra lore, no side quests.
