doesn't happen to be included before this header. This header was missed in previous cleanups because it didn't include <sys/ioctl.h> or <sys/ioccom.h>. Clean it now: - #include <sys/types.h> since it is necessary to make the header self- sufficient (there are a couple of u_char's). - uniformized idempotency ifdef. Copied the style in the 4.4Lite ioctl headers.
