But you'd better use uint8_t in you kernel programming practice rather than use __u8 directly. Because asm directory varies on different architecture. The program will get better portability by using uint8_t.In an other words, uint8_t provide more abstraction for '1 byte' type. -- Adam Jiang ------------------------------------------ e-mail:[email protected] -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to [email protected] Please read the FAQ at http://kernelnewbies.org/FAQ
