Right and you can deal with it easily. Just introduce the mm_zero_struct_page earlier along with its user in "stop zeroing ..." I think that moving the zeroying in one go is more reasonable than adding it to __init_single_page with misleading numbers and later dropping the zeroying from the memmap path. -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
