💅 usb_autopm_...e_no_suspend(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel has its own manual, and yes it's iconic. Today's main character is usb_autopm_put_interface_no_suspend, which lowkey has the longest name ever but slays anyway. 🫶

🌸 NAME 🌸

usb_autopm_put_interface_no_suspend — decrement a USB interface's PM-usage counter. that's it, that's the whole job. 💅

🦋 SYNOPSIS 🦋

void usb_autopm_put_interface_no_suspend (struct usb_interface *intf );

🎀 ARGUMENTS 🎀

  • intf — the usb_interface whose counter should be decremented. this is the one you're doing the vibe check on, so make sure it's the right one, ok?

✨ DESCRIPTION ✨

so here's the tea, bestie: this routine decrements intf's usage counter but does not carry out an autosuspend. like, she updates the bookkeeping and then just… doesn't take the nap. no cap. 🫶

the way that this routine can run in atomic context — she's flexible, she's low maintenance, she's literally built different. 🧚

fr fr though: no autosuspend happens here. if you were expecting the interface to actually get suspended, this is not that function, bestie. 😭

👑 SEE ALSO 👑

kernel file ./drivers/usb/core/driver.c and the whole USB driver friend group:

that's the whole squad. they all live together in ./drivers/usb/core and honestly? iconic household. 🌈

alright bestie, that's the page! 🎀 sourced from ./drivers/usb/core, and the date on this one is October 2026 — so future-coded of her. mwah, go decrement those counters responsibly 💖💅
