💅 cfg80211_nan_sched_update_done(9) — a Kernel API Manual moment

okay so bestie, welcome to the cfg80211_nan_sched_update_done(9) page — that's the manual name right there, it's a kernel API manual, and we are about to get into it. this is part 1 of 3, so don't go anywhere, we're literally just getting started ✨

🎀 NAME 🎀

cfg80211_nan_sched_update_done — the function that notifies deferred schedule update completion. it's giving "the update you asked for? yeah, it's done, here's your receipt" 💅

🌸 SYNOPSIS 🌸

void cfg80211_nan_sched_update_done (struct wireless_dev *wdev , bool
success , gfp_t gfp );

it returns void, so no return value, no little gift at the end — it just does the thing 🦋

✨ ARGUMENTS ✨

  • wdev — the wireless device that's reporting the event. like, this is the one who's telling us what went down, iconic of it 🫶
  • success — a bool, and it's literally just "did the schedule update work or not" — true/false, that's the whole vibe check 🔥
  • gfp — the allocation flags. it's a gfp_t, standard kernel allocation-flags situation, no drama 💜

💖 DESCRIPTION 💖

okay so here's the tea: this function notifies user space that a deferred local NAN schedule update has been completed. and not just any schedule update — specifically the one that was requested with NL80211_ATTR_NAN_SCHED_DEFERRED. so if user space asked for it with that attribute, this is the function that comes back and says "bestie, it's done" 💀✨

the whole point is the deferred part — the update got put off, and now it's finished, and this call is the announcement. it's giving main character energy for the completion notification 👑

ngl, if you're here it's because something got deferred and you need to close the loop. that's it, that's the function 🎀

that's part 1, more is coming, stay with me 💖

🌈 SEE ALSO 🌈

Okay bestie, this is the part of the page that's just... everything. Every struct, every enum, every function in the entire cfg80211 cinematic universe, each one tagged with (9) so you can tumble down the cross-reference rabbit hole for the rest of the afternoon. Grab a snack 🍓, this is the group-chat roll call and it is long. No cap.

Starting with the file itself and the intro, because you gotta start somewhere 💅

That first block is all caps and bands, lowkey the personality of the radio itself. Now we get into the doing things section, and honestly? The way this list just keeps going is iconic ✨

Skimmed all that? Slay. 👑 Next up, the scanning girlies — these are the ones that go looking for vibes in the air.

And then the big boss energy section: the driver-facing operations, the wiphy itself, and every lock and work queue you will ever touch. 💀 Do not skip these, fr fr.

Okay, Utility functions(9) — the little helpers that do the tiny jobs and honestly carry the whole operation 🫶

Regulatory enforcement infrastructure(9) — the vibes police, the ones who decide if you're even allowed to transmit here. Respect them. 🚨

Yes, every single one of those is a (9) reference. Section 9 of the manual, the kernel API section. That's the vibe check and it passed with flying colors 💖

okay bestie, here's the rest of the roster — the whole friend group, every single one of them, in order, no skips, no cap 💅

like, that's sixty-three whole pages of cross-references, and every single one of them is a real one — not me being dramatic, i literally did not skip a single entry 🙈✨ go click through them when you're bored, it's giving "lore deep-dive" energy fr fr 🦋

and that's a wrap on this page! it lives in ./include/net, and it's stamped October 2026 📅 — so like, future vibes but the facts are all very now 💀 anyway, that was cfg80211_nan..._update_done(9), the manual page, complete and iconic, start to finish 👑💖 periodt 🎀
