You can drop this patch. This turned out to be a race in xpmem. It "appeared" as if it were a race in get_task_mm, but it really is not. The current->mm field is cleared under the task_lock and the task_lock is grabbed by get_task_mm. I have been testing you v15 version without this patch and not encountere the problem again (now that I fixed my xpmem race).
