💅 reset_control_bulk_get_exclusive_released — from the Kernel API Manual, bestie ✨

okay so you know how getting one reset controller is a whole thing? imagine doing that for a whole squad of them at once, and they're all on temporary-exclusive vibes. yeah. that's this function. her name is reset_control_bulk_get_exclusive_released and she ate 🎀

✨ NAME ✨

reset_control_bulk_get_exclusive_released — lookup and obtain temporarily exclusive references to multiple reset controllers. plural. a whole friend group of reset controls. 🫶

🔥 SYNOPSIS 🔥

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

like, she takes three things and she gives you back an int. no cap.

🌸 ARGUMENTS 🌸

  • dev — the device that's gonna get reset by the controller. main character device energy 👑
  • num_rstcs — how many entries are chillin' in the rstcs array. literally just the count, bestie 💅
  • rstcs — array of struct reset_control_bulk_data with the reset line names already set. that's the whole point — the names are pre-filled, you're not naming them here 🦋

💖 DESCRIPTION 💖

So what she actually does: she fills the rstcs array with pointers to exclusive reset controls, then returns 0 if everything slayed. ✨ If it didn't slay, you get an IS_ERR condition containing errno — so pls check that, don't just ignore it 😭

🚨 okay this part is IMPORTANT so read it twice: reset-controls returned by this function must be acquired via reset_control_bulk_acquire before they can be used, and they should be released via reset_control_bulk_release afterwards. like, that's not optional. that's the whole lifecycle. don't leave them hanging 🙈

🦋 SEE ALSO 🦋

Kernel file ./include/linux/reset.h, plus all her cousins and neighbors (yes there are SO many, she's from a big family, iykyk 💀):

💜 and that's the whole page, babe. go acquire your resets responsibly. periodt.

um okay sign-off time 🌈 — this lil gem lives in ./include/linux, dated October 2026, and it's still called reset_contr...ive_released(9) in the corner because the header refused to be fully typed out 💀 bye bestie, ily, go read your errno ✨🎀
