I wasn't talking about headers. Take modules/access/rtp/input.c as an
example, struct iovec is clearly used there but sys/uio.h is not included.

That's just one of many examples. Compare `grep -r "struct iovec"` to
`grep -r "sys/uio.h"`.

That's why I would like to get rid of the #include <sys/uio.h> in the
patch and just define IOV_MAX.
