✨ devm_delayed_work_autocancel — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual 💅 this page is literally all about devm_delayed_work_autocancel, and ngl it's kind of a glow-up for delayed work. stay with me 🫶

🌸 NAME 🌸

devm_delayed_work_autocancel — resource-managed delayed work allocation ✨

🦋 SYNOPSIS 🦋

int devm_delayed_work_autocancel (struct device *dev , struct
       delayed_work *w , work_func_t worker );

like, that's the whole signature, no cap 🔥

💖 ARGUMENTS 💖

  • dev — the device whose lifetime the work is bound to 👑 it's giving "this work belongs to you, bestie"
  • w — the work item to be queued 🌈
  • worker — the worker function 🧚

🎀 DESCRIPTION 🎀

so the vibe here is: this initializes delayed work that gets automatically cancelled when the driver is detached ✨ iconic behaviour, honestly.

a few drivers need delayed work that must be cancelled before the driver is detached, to avoid accessing removed resources 😭 like, you do NOT want your work touching stuff that's already gone. that's the danger zone, fr fr.

devm_delayed_work_autocancel can be used to omit the explicit cancellation when the driver is detached 💅 so you don't have to write the cleanup yourself — it's handled. slay.
