Name:moyo_print_header - Get header line of audit log.*@r: Pointer to "struct tomoyo_request_info".* Returns string representation.* This function uses kmalloc(), so caller must kfree() if this function* didn't return NULL.

Proto:static char *tomoyo_print_header(struct tomoyo_request_info *r)

Type:char
