✨ svc_rdma_iov_write(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this lil page is all about svc_rdma_iov_write and honestly it's giving "small function, big responsibilities" energy. let's get into it 🫶

🌸 NAME 🌸

svc_rdma_iov_write — construct RDMA Writes from an iov 🦋

like, it literally builds RDMA Write operations out of an iov. that's the whole vibe. no cap.

✨ SYNOPSIS ✨

int svc_rdma_iov_write (struct svc_rdma_write_info *info , const struct
       kvec *iov );

so you're calling it with a struct svc_rdma_write_info * and a const struct kvec * and it hands you back an int. iconic signature, tbh 👑

🎀 ARGUMENTS 🎀

  • info — pointer to write arguments 💖 this is where all the write deets live.
  • iov — the kvec to write 🌟 like, the actual data chunk you're pushing out.

🔥 RETURN 🔥

okay so here's the tea on what comes back ☕

  • On success, returns zero ✅ slay, we love a clean exit.
  • -E2BIG — if the client-provided Write chunk is too small 😭 like the chunk literally cannot hold it, not enough room bestie.
  • -ENOMEM — if a resource has been exhausted 💀 out of memory/resources, rough.
  • -EIO — if an rdma-rw error occurred 🙈 something went sideways at the rdma-rw level.
bestie pls check that return value, fr fr. zero is the only happy one here 💜
