💅 nlm_svc_decode_nlm_testargs — bestie's guide to decoding a nlm_testargs argument

okay so real talk, this is a Kernel API Manual page (that's the manual name, hi 👋) and it's about one tiny little function that does one tiny little job. let's get into it 💖

✨ NAME ✨

nlm_svc_decode_nlm_testargs — literally just "decode a nlm_testargs argument". that's the whole vibe. it takes the raw wire data and turns it into the actual test-args struct, no cap 🎀

🌸 SYNOPSIS 🌸

bool nlm_svc_decode_nlm_testargs (struct svc_rqst *rqstp , struct
       xdr_stream *xdr );

yes bestie, it returns a bool, and yes, the two params are exactly rqstp and xdr — copy them character for character, do not be cute with it 🙈

🦋 ARGUMENTS 🦋

  • rqstp — the RPC transaction context 🫶 this is the "who/what/where" of the request that just landed on your doorstep.
  • xdr — the source XDR data stream ⭐ this is the raw wire data you're reading from. like the unopened group chat, and this function is the read receipt.

💜 DESCRIPTION 💜

so here's the whole deal — the return values are the entire personality of this function:

  • true — procedure arguments decoded successfully ✅ slay, it ate, nothing else to say 💅
  • false — decode failed 💀 the wire data said no thank you, and you handle it accordingly.
fr fr, don't ignore the false. it means the decode failed. that's not a vibe, that's an error path 😭

👑 SEE ALSO 👑

okay this is the friend group, and yes there are a LOT of them — the kernel file is ./fs/lockd/nlm3xdr_gen.c and these are all its besties:

notice how the decoders and the encoders are all here? it's giving ✨ full circle ✨ — one reads from the wire, the other writes to it, and they all live under ./fs/lockd together like one big happy directory 🧚🌈

🎀 the cute little sign-off 🎀

this page lives in ./fs/lockd, it's dated October 2026, and it's the nlm_svc_decode_nlm_testargs(9) page — go forth and decode responsibly, bestie 🍓🔥
