hcd_buffer_destroy(9)

💅 hcd_buffer_destroy(9) — from the Kernel API Manual, bestie 💖

okay so real talk, this one is a little kernel function that lives in the Kernel API Manual, and she's short but she MATTERS. her whole job? cleaning up after hcd_buffer_create so your kernel doesn't just leak buffer pools into the void. iconic behavior honestly 🎀

✨ NAME ✨

hcd_buffer_destroy — deallocate buffer pools 🧹💜

✨ SYNOPSIS ✨

void hcd_buffer_destroy (struct usb_hcd *hcd);

✨ ARGUMENTS ✨

• hcd — the bus whose buffer pools are about to get destroyed, like, gone-gone 🫶 this is the <italic>struct usb_hcd *</italic> you're handing over so her pools can be freed.

✨ CONTEXT ✨

task context, might sleep 😴💤

ngl bestie, "might sleep" is your cue that you're not in some atomic/interrupt situation here — you're in task context, so the kernel is allowed to nap. don't fight it.

✨ DESCRIPTION ✨

This frees the buffer pools created by hcd_buffer_create. that's it. that's the whole vibe 🦋 she's the cleanup main character — hcd_buffer_create(9) builds the pools, and hcd_buffer_destroy shows up at the end to slay them back out of existence. no cap, every pool gets freed 🔥

✨ SEE ALSO ✨

• Kernel file ./drivers/usb/core/buffer.c
• hcd_buffer_create(9)

and that's the whole page, bestie, you ate that 💅⭐ source vibes come from ./drivers/usb/core, dated October 2026 — go forth and free those pools responsibly 🌸👑
