Finally I resolved this problem. It seems a bug in kernel, which is caused by using 'enum' in a struct in Linux's kernel.
Different compilers use different data types on 'enum' (maybe 'char' or 'int') In my android, the kernel's 'enum' size is 4, while the size of 'enum' in ELF binarys is 1. Then some options in kernel is incorrect. It's really a bad idea to use 'enum' in a struct, especially whichwill be used by other applications outside the module which defines it, but unfortunately there are still some misuses in Linux's kernel.
