📦 version 7.3.1, in nixpkgs unstable

💅 svc_rdma_pages_write(9) — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is svc_rdma_pages_write from the Kernel API Manual and honestly? she's lowkey iconic. sit down, grab a strawberry drink 🍓, and let me tell you about the girl whose whole job is Constructing RDMA Writes from pages. main character energy fr fr.

🎀 NAME 🎀

svc_rdma_pages_write — Construct RDMA Writes from pages 💖

like... that's literally her. that's the assignment. she takes pages and she constructs RDMA Writes out of them. no cap.

✨ SYNOPSIS ✨

int svc_rdma_pages_write (struct svc_rdma_write_info *info , const
       struct xdr_buf *xdr , unsigned int offset , unsigned long length );

she returns an int, and honestly the way she takes four arguments? multi-talented. we stan. 👑

🦋 ARGUMENTS 🦋

the four besties she rolls with, in order, no line-cutting:

  • info — pointer to write arguments. that's her little bag of info, she carries it everywhere 🫶
  • xdr — the xdr_buf with pages to write. this is the actual material she's working with, the pages bestie, the whole point of the function 💅
  • offset — offset into the content of xdr. like starting a playlist partway through — she's skipping to this spot 🎧
  • length — number of bytes to write. how much of the vibe she's committing to. count them, don't guess ⭐

🌸 RETURN 🌸

okay so this is the part where you find out how it went:

  • On success — returns zero. slay. perfect. nothing to fix 💖
  • -E2BIG — if the client-provided Write chunk is too small. like trying to fit your whole wardrobe into a carry-on 😭 it does NOT fit and she will tell you
  • -ENOMEM — if a resource has been exhausted. out of resources, out of vibes, out of everything 💀
  • -EIO — if an rdma-rw error occurred. something went feral in the rdma-rw layer, not her fault, but she's reporting it 🙈
ngl, negative returns are not a vibe, but at least she tells you exactly which negative return it is. transparency queen. 🔥
