Hello, There is a small bug __kmalloc in DDE Linux26: when the memory is allocated by ddekit_large_malloc, the memory isn't set to zero even when __GFP_ZERO is set. It could cause some potential problems. For example, when a programmer calls kzalloc to allocate memory, he wants a piece of memory that has been set to zero. When I ran e1000 in DDE Linux26, this bug caused a big problem. Best regards, Zheng Da
