BUS_GENERIC_DETACH(9)

✨ NAME ✨

okay bestie, this is BUS_GENERIC_DETACH(9) from the Kernel Developer's Manual, and it's literally the generic implementation of DEVICE_DETACH for buses 💅

bus_generic_detach — generic implementation of DEVICE_DETACH for buses

🎀 SYNOPSIS 🎀

#include <sys/param.h>
#include <sys/bus.h>

int
bus_generic_detach(device_t dev);

🦋 DESCRIPTION 🦋

so this function gives you an implementation of the DEVICE_DETACH(9) method that most bus code can use. no cap.

it uses bus_detach_children(9) to detach drivers from all child devices, and it gives them a chance to veto the detach request — yes, they can absolutely say “not today” 🙈.

if bus_detach_children() succeeds, then bus_generic_detach() calls device_delete_children(9) to delete all child devices. iconic cleanup behavior, honestly ✨.

💖 RETURN VALUES 💖

Zero is returned on success. otherwise, an appropriate error is returned. that's the vibe check, fr fr 🫶.
