I don't agree with you for the point that the conditions were right.

The definition of s->buf is "void *buf[AF_NCH]" which means that buf
is an array which contains AF_NCH void pointers. Therefore, the size
of s->buf is immutable, and its address is always equal to that of
the struct plus an offset, which indicates that the value of s->buf
here can never equal to a non-zero value except s has a specific

However, you are right that for the current code, the conditions can
be removed directly.
