📦 version 7.3.1, in nixpkgs unstable

💅 nlm_svc_decode_nlm_cancargs(9) — like, the Kernel API Manual page you didn't know you needed 🦋

okay so bestie, welcome to section 9 of the Kernel API Manual, and today's main character is nlm_svc_decode_nlm_cancargs. yes that's a mouthful, yes she ate, and yes we're gonna get through it together 🫶

✨ NAME ✨

nlm_svc_decode_nlm_cancargs — decode a nlm_cancargs argument. that's it. that's the whole job. she decodes, she slays, she goes home 💅

⭐ SYNOPSIS ⭐

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

look at her go. returns a bool, takes two little friends. iconic signature fr fr 💖

🎀 ARGUMENTS 🎀

  • rqstp — the RPC transaction context, a.k.a. the whole situation you're operating inside. think of it as the group chat where the transaction lives 🌸
  • xdr — the source XDR data stream. this is where the actual bytes come from, the raw material, the tea ☕

🔥 DESCRIPTION 🔥

so what does she actually do? she tries to decode the procedure arguments off that XDR stream, and then she tells you how it went. return values, no cap:

  • true — procedure arguments decoded successfully. we love a win 👑 ✨
  • false — decode failed. it's giving tragedy, but at least you know 😭
that's literally the whole contract — nothing hidden, nothing extra. true means slay, false means the data said no 🙈

🌈 SEE ALSO 🌈

go look at the actual kernel file, bestie: ./fs/lockd/nlm3xdr_gen.c 🧚 — and while you're in the neighborhood, here are all her siblings and cousins, every single one, no gatekeeping:

okay that's a whole family reunion and honestly? obsessed 💜

and that's the page, bestie 🍓 huge shoutout to the ./fs/lockd source, kernel API manual version vibes, dated October 2026 — she's from the future and she's still decoding args. periodt 💀✨
