request_firm...owait_cancel(9)

📦 version 7.3.1, in nixpkgs unstable

hiii bestie 💖 welcome to the request_firm...owait_cancel(9) page — it's part of the Kernel API Manual and it's literally all about cancelling an async firmware request. no cap, it's short but it matters. let's get into it ✨

🌸 NAME 🌸

request_firmware_nowait_cancel — cancel an async firmware request 🫶

💅 SYNOPSIS 💅

void request_firmware_nowait_cancel (struct device *device , void *context , void (*cont)(const struct firmware *fw, void *context) );

that's the whole signature, bestie — memorize it or don't, but it's right there 💀

🎀 ARGUMENTS 🎀

  • device — the device for which the firmware is being loaded. like, which device are we doing this for? 👑
  • context — the context passed to request_firmware_nowait. it's the same context, just vibing through 🦋
  • cont — the callback passed to request_firmware_nowait. this is the function that gets called when things are ready ✨

🔥 DESCRIPTION 🔥

okay so here's the tea ☕: this function cancels a pending request_firmware_nowait request for device, context and cont. like, it's the cancel button for that async request, periodt.

if the associated work has already started, this function waits until the callback has returned. so it's not gonna just dip — it waits for the callback to finish, no cutting corners 💅

if the callback has already completed, this function does nothing. literally nothing. it's a no-op at that point, and that's iconic.

⚠️ bestie, this function may sleep. yes, may sleep — so it's not one of those non-blocking girlypops, plan accordingly 💤
