💖 free_workqueue_attrs(9) 💖

okay bestie, welcome to free_workqueue_attrs — yes, that's the manual page name, it's giving very "kernel API manual" energy and honestly? iconic. this one's a tiny little function from the Linux kernel docs and she does Exactly One Job 🎀

✨ NAME ✨

free_workqueue_attrs — the gal whose whole personality is freeing a workqueue_attrs 🦋

---

🌸 SYNOPSIS 🌸

void free_workqueue_attrs (struct workqueue_attrs *attrs );

that's it. that's the whole mood. it returns void, aka nothing, aka she's not here to give you a value back, she's here to ✨release✨ 😌

---

🧚 ARGUMENTS 🧚

• attrs — the workqueue_attrs you want to free. that's the one. hand her over, she's done 💅

---

⭐ DESCRIPTION ⭐

so basically this is the undo button for alloc_workqueue_attrs. yep. that's the entire description and ngl it ate 🫶

you allocated those workqueue_attrs, now you're done with them, so you call free_workqueue_attrs and she takes them off your hands. no cap, no drama, no leftover allocation. periodt 💜
