[PATCH] usb: fixup usb so it uses struct pid
The problem with remembering a user space process by its pid is that it is possible that the process will exit, pid wrap around will occur. Converting to a struct pid avoid that problem, and paves the way for implementing a pid namespace. Also since usb is the only user of kill_proc_info_as_uid rename kill_proc_info_as_uid to kill_pid_info_as_uid and have the new version take a struct pid. Signed-off-by: Eric W.
