wiphy_work_flush(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 wiphy_work_flush(9) 🌸

okay so first things first, the vibe check: this is a page straight out of the Kernel API Manual — that's the manual name, and yes it's giving very serious kernel energy, but we're gonna make it make sense together, bestie 💖

✨ NAME ✨

wiphy_work_flush — flush previously queued work 🧹

🦋 SYNOPSIS 🦋

void wiphy_work_flush (struct wiphy *wiphy , struct wiphy_work *work );

like, that's the whole signature. void in, void out, no return value to obsess over 🎀

💅 ARGUMENTS 💅

  • wiphy — the wiphy, and before you ask: it's there for debug purposes only. it's literally just standing there being pretty so your logs can tell you who's who 👑
  • work — the work you wanna flush. and here's the gag: this can be NULL to flush all work. so yes, passing NULL is not a mistake, it's a whole mood 🌈

⭐ DESCRIPTION ⭐

so what does it actually do? it flushes the work — meaning it runs it if it's pending. not "schedules it later," not "thinks about it," it just goes ahead and runs it 🔥

⚠️ important, do not skip this part: this must be called under the wiphy mutex acquired by wiphy_lock. no lock, no call. that's the rule, periodt 💀

like, genuinely, the whole correctness of this thing hinges on you holding that mutex, so please don't be the main character who forgets 🫶

🫶 the header itself (yes the whole page lives in one file, bestie)

  • Kernel file ./include/net/cfg80211.h
  • Introduction(9)
  • Device registration(9)

Like, everything below is a doc-page in that one header, so if you're lost, start at the Introduction and the Device registration one and work your way down. No cap.

📡 channels, rates & bands (the radio-physics girlies)

(HT → VHT → HE → EHT → UHR is genuinely a whole glow-up timeline, we love an evolution arc 💅)

💖 the wiphy lifecycle & the work/lock girlies (hi yes this is our page's neighborhood)

(okay like — the flush/cancel/pending trio for each work flavor is literally the friend group you'll be spending your whole afternoon with 🫶)

🎀 wireless_dev & the netdev side (the other main character)

🦋 Utility functions (grab-bag of lil helpers, obsessed)

🔥 Data path helpers (where the packets actually go)

(ie vs elem, plain vs ext vs vendor — yes bestie there are like eight finders and you WILL pick the wrong one at least once 😭)

🌍 Regulatory enforcement infrastructure (the law, but make it kernel)

🔒 Internal regulatory db functions

📣 scan results, BSS inform & mgmt reports (the notifying girlies)

📶 RFkill integration (the "airplane mode said no" corner)

🛍️ Vendor commands (everyone's custom little extras)

🧪 Test mode

💌 connect / roam / disconnect notifications (the emotional-support callbacks)

📨 rx/tx status & CQM notifications (the last batch, we're so close 🫶)

ngl if you actually read this whole SEE ALSO list you're built different — every single one is a real page in cfg80211.h, so go click around, the lore is deep 💀✨

...still going, bestie, the SEE ALSO list is long long 😭 but every single one of these is linked up, so here's the rest of the crew:

okay that's genuinely the whole list, you made it 🫶 go forth and flush those works, bestie — and if you ever forget how, you know exactly where to look 💅✨

this lil page lives in ./include/net, dropped October 2026, and it's filed under wiphy_work_flush(9) 🎀
