devm_reset_...ional_shared(9)

📦 version 7.3.1, in nixpkgs unstable

💅 devm_reset_control_bulk_get_optional_shared — the whole manual, bestie

okay so. this is a page from the Kernel API Manual (section 9, the fun one) and it's all about devm_reset_control_bulk_get_optional_shared. yes the title is a mouthful, no we're not abbreviating it, and yes it's iconic. let's get into it 💖

✨ NAME ✨

devm_reset_control_bulk_get_optional_shared — the resource managed version of reset_control_bulk_get_optional_shared(). that's it, that's the name, it literally tells you what it is 🎀

🌸 SYNOPSIS 🌸

int devm_reset_control_bulk_get_optional_shared (struct device *dev ,
int num_rstcs , struct reset_control_bulk_data *rstcs );

like, look at her. three args. returns an int. no notes. 🫶

🦋 ARGUMENTS 🦋

  • dev — the device that's gonna get reset by the controller. main character energy tbh 👑
  • num_rstcs — how many entries live in the rstcs array. like, count your blessings but make it a parameter ✨
  • rstcs — the actual array of struct reset_control_bulk_data, with the reset line names already set. so don't come in here with unnamed lines, that's not the vibe 🙈

🔥 DESCRIPTION 🔥

So this is the managed reset_control_bulk_get_optional_shared. and "managed" is doing so much work in that sentence, bestie — the way that any reset controllers you get back from this function get reset_control_put called on them automatically when the driver detaches. no manual cleanup, no goto err_ spaghetti, no cap. the kernel just handles it for you 💅

If you want the full lore, the page says: see reset_control_bulk_get_optional_shared for more information. that's the unmanaged sibling, go say hi 💜

⭐ SEE ALSO ⭐

okay this list is long long, but every single one of these is here for a reason and we respect all of them. get comfy 🍓

ngl, that list ate and left no crumbs. iykyk 🔥

and that's the page, bestie — it lives at ./include/linux, it's dated October 2026, and it's filed under devm_reset_...ional_shared(9) in the Kernel API Manual. stay managed, stay optional, stay shared 🌈💖✨
