Hi,


On my up to date current box I am noticing memory leak complaints when
unload the usb module.

This is from a straight load/unload:

[dev7b]# kldload usb
uhci0: <Intel 82801AA (ICH) USB controller> port 0x1820-0x183f irq 11 at
device 31.2 on pci0
uhci0: [GIANT-LOCKED]
uhci0: [ITHREAD]
usb0: <Intel 82801AA (ICH) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: <Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0
uhub0: 2 ports with 2 removable, self powered
[dev7b]# kldunload usb
uhub0: detached
usb0: detached
uhci0: detached
Warning: memory type USBdev leaked memory on destroy (5 allocations,
2560 bytes leaked).
Warning: memory type USB leaked memory on destroy (13 allocations, 1248
bytes leaked).
