💅 devm_reset_control_get_optional_exclusive(9) — the Kernel API Manual one 🎀

Okay so bestie, this page lives in the Kernel API Manual (yes, that's the manual name, we're fancy now ✨) and it's all about one very specific little function. Buckle up, it's giving "short page, big name" energy.

🌸 NAME 🌸

devm_reset_control_get_optional_exclusive — which is literally the resource managed version of reset_control_get_optional_exclusive(). That's the whole name. It's long. She ate though. 💅

✨ SYNOPSIS ✨

struct reset_control * devm_reset_control_get_optional_exclusive (struct
device *dev , const char *id );

Look at her. Two args, one struct reset_control * coming back at you. Iconic. 🌟

🫶 ARGUMENTS 🫶

  • dev — the device that's gonna get reset by the controller. That's her whole job, she's the reset-ee. 😌
  • id — the name of the reset line. Yes bestie, it's a name. Strings only, no cap. 🎀

💖 DESCRIPTION 💖

So this is the managed reset_control_get_optional_exclusive. The "managed" part is the good part, okay? For any reset controllers that come back out of this function, reset_control_put gets called automatically when the driver detaches. You don't have to remember to clean up. You literally cannot forget. She handles it. 💅✨

Like a bestie who venmos you back without being asked. That's the energy. 🫶

And for the full lore? Go read reset_control_get_optional_exclusive — that's where the real info lives. This page is the spin-off. 😭

🦋 SEE ALSO 🦋

Okay this is the part where the page goes full group-chat-adds-everyone. Every single one of these, no skips, no cap. 💀

Also, the kernel file that started it all: ./include/linux/reset.h 📁 — that's the source of truth, iykyk.

🧚 And that's the whole page, bestie. No exit statuses, no signals, no warnings — she's a simple queen. 🌈

💜 mwah 💜 This page ships from ./include/linux and is dated October 2026 — so like, future icon behaviour, we love to see it. 👑✨
