The <sys/termios.h> header file is hardlinked to <termios.h>. It contains both the structures and the flag definitions, but also the C library interface that's implemented by the C library. This header file has the typical problem of including too many random things and being badly ordered. Instead of trying to fix this, decompose it into two header files: - <sys/_termios.h>, which contains struct termios and the flags. - <termios.h>, which includes <sys/_termios.h> and contains the C library interface. This means userspace has to include <termios.h> for struct termios, while kernelspace code has to include <sys/tty.h>. Also add a <sys/termios.h>, which prints a warning message before including <termios.h>. I am aware that there are some applications that use this header file as well.
