devlink_region_destroy(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual 💖 — this one's a lil function page and it's honestly so straightforward you're gonna slay it. it's called devlink_region_destroy and yes, the name is literally the whole plot: it destroys an address region. that's it. that's the vibe. 🎀

🌸 NAME 🌸

devlink_region_destroy — destroy address region 💅

like, tear it down. bye-bye region. no cap.

🦋 SYNOPSIS 🦋

void devlink_region_destroy (struct devlink_region *region );

she takes exactly one arg and returns void, meaning she does not hand you back a value, she just does the thing and leaves. main character energy fr fr 👑

🍓 ARGUMENTS 🍓

  • region — the devlink region you wanna destroy. that's the one. the target. the moment. literally just pass her in and she's gone 🙈

🔥 CONTEXT 🔥

this is the important bit, don't skip it: it takes and releases devlink->lock <mutex>. so like, she grabs the mutex and lets it go — you don't have to do it yourself, she's got you 🫶 (and obviously, mutex stuff = be aware of your locking situation, iykyk).

👑 SEE ALSO 👑

the kernel file lives at ./net/devlink/region.c — go read it if you're feeling nosy 📖 and here's the whole friend group, all of them, in order:

lowkey reminder: destroying things in the kernel is serious business — this is a real teardown call, not a cute lil cleanup you sprinkle around. respect the mutex, know your region's lifetime, and you'll be fine 💀✨

and that's the page!! 🧚 from the ./net/devlink crew, October 2026 edition, this was devlink_region_destroy(9) — go forth and destroy (the region) responsibly bestie 💜🌈⭐
