💅 nfsd_nl_server_stats_get_dumpit(9) — Kernel API Manual 🎀

okay bestie, this is a page from the Kernel API Manual (section 9), and the star of the show is nfsd_nl_server_stats_get_dumpit — the function that dumps NFS server statistics. it's giving "kernel internals but make it cute". let's get into it 💖

✨ NAME ✨

nfsd_nl_server_stats_get_dumpit — dump NFS server statistics 📊

🌸 SYNOPSIS 🌸

int nfsd_nl_server_stats_get_dumpit (struct sk_buff *skb , struct
       netlink_callback *cb );

literally that's the whole signature. short, sweet, slays. 🫶

🦋 ARGUMENTS 🦋

  • skb — the reply buffer 💌 like, this is where the answer goes, bestie.
  • cb — netlink metadata and command arguments 🗂️ the whole context bundle, no cap.

👑 DESCRIPTION 👑

okay so the server-stats object gets emitted across one or more netlink messages. it's not always a one-and-done situation — it's giving "multi-part story arc" ✨

here's the tracking situation, and it's honestly iconic:

  • cb->args[0] tracks the current section 📍
  • cb->args[1] tracks the entry index within that section 🔢

so if a section does not fit in the current message, it just gets resumed in the next one. no drama, no lost data, just a little continue-where-we-left-off moment. periodt. 💅

the scalar counters are small, so they get emitted once, in the first message. and then userspace merges the attributes from every message. teamwork makes the dream work fr fr 🫶🌈

Returns the size of the reply, or a negative errno 😭 (yes, the classic "size or sadness" return value, iykyk).
