Serge Hallyn d178bc3a70 user namespace: usb: make usb urbs user namespace aware (v2) ... Add to the dev_state and alloc_async structures the user namespace corresponding to the uid and euid. Pass these to kill_pid_info_as_uid(), which can then implement a proper, user-namespace-aware uid check. Changelog: Sep 20: Per Oleg's suggestion: Instead of caching and passing user namespace, uid, and euid each separately, pass a struct cred. Sep 26: Address Alan Stern's comments: don't define a struct cred at usbdev_open(), and take and put a cred at async_completed() to ensure it lasts for the duration of kill_pid_info_as_cred().
