    [PATCH] Don't pass boot parameters to argv_init[] · 9b41046c
    OGAWA Hirofumi 提交于
    The boot cmdline is parsed in parse_early_param() and
    parse_args(,unknown_bootoption).
    
    And __setup() is used in obsolete_checksetup().
    
    	start_kernel()
    		-> parse_args()
    			-> unknown_bootoption()
    				-> obsolete_checksetup()
    
    If __setup()'s callback (->setup_func()) returns 1 in
    obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
    handled.
    
    If ->setup_func() returns 0, obsolete_checksetup() tries other
    ->setup_func().  If all ->setup_func() that matched a parameter returns 0,
    a parameter is seted to argv_init[].
    
    Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
    If the app doesn't ignore those arguments, it will warning and exit.
    
    This patch fixes a wrong usage of it, however fixes obvious one only.
