The new USBDEVFS_DROP_PRIVILEGES ioctl allows a process to voluntarily
relinquish the ability to issue other ioctls that may interfere with
other processes and drivers that have claimed an interface on the

Hi everyone,
This patch introduces a new ioctl, USBDEVFS_DROP_PRIVILEGES,
to voluntarily forgo the ability to issue ioctls which may
interfere with other users of the USB device.
This feature allows a privileged process (in the case of Chrome OS,
permission_broker) to open a USB device node and t
