    mm/gup: Switch all callers of get_user_pages() to not pass tsk/mm · d4edcf0d
    Dave Hansen 提交于
    We will soon modify the vanilla get_user_pages() so it can no
    longer be used on mm/tasks other than 'current/current->mm',
    which is by far the most common way it is called.  For now,
    we allow the old-style calls, but warn when they are used.
    (implemented in previous patch)
    
    This patch switches all callers of:
    
    	get_user_pages()
    	get_user_pages_unlocked()
    	get_user_pages_locked()
    
    to stop passing tsk/mm so they will no longer see the warnings.
