nfsd_set_nrthreads(9)

📦 version 7.3.1, in nixpkgs unstable

💅 nfsd_set_nrthreads 💅

okay so bestie, welcome to the kernel-side glow-up manual for nfsd_set_nrthreads — it's a 9-section Kernel API Manual page, and honestly? she's iconic. she's literally the function that sets the number of running threads in the net's service. no cap. 🧵✨

✨ SYNOPSIS ✨

int nfsd_set_nrthreads (int n , int *nthreads , struct net *net );

that's the whole vibe right there. three args, one int coming back at you. obsessed. 🫶

🎀 ARGUMENTS 🎀

  • n — the number of array members in nthreads. basically: how many entries are you actually handing me, bestie? 👀
  • nthreads — an array of thread counts, one for each pool. yes, each pool. she's plural. 💅
  • net — the network namespace to operate within. this is the neighborhood she's working in. 🏘️

🌸 DESCRIPTION 🌸

so what does she do? this function alters the number of running threads for the given network namespace — in each pool. all of them. every single one. main character energy across the board. 👑

now the messy part, and listen up because this is giving "read the fine print" energy:

  • if you pass an array longer than the number of pools, the extra pool settings are ignored. like, they're just standing there, not invited to the party. 🙈
  • if you pass an array shorter than the number of pools, the missing values are interpreted as 0's. no value? no threads. simple as that. 💀
and then the return value, because of course: returns 0 on success or a negative errno on error. 0 = slay. negative errno = something went sideways and she's telling you in errno-speak. 😭

and that's the page, bestie!! 🎀 this one ships out of ./fs/nfsd, dated October 2026, and it's the nfsd_set_nrthreads(9) page in the Kernel API Manual — thanks for reading, mwah, bye!! 🌈⭐💜
