pid_namespace: pidns_get() should check task_active_pid_ns() != NULL
pidns_get()->get_pid_ns() can hit ns == NULL. This task_struct can't go away, but task_active_pid_ns(task) is NULL if release_task(task) was already called. Alternatively we could change get_pid_ns(ns) to check ns != NULL, but it seems that other callers are fine. Signed-off-by: Oleg Nesterov <oleg@redhat.com> Cc: Eric W.
