Hello,
is there a reason why the m_length() function defined in "sys/mbuf.h"
needs a local variable "m0". I think it could look like this:
static __inline u_int
m_length(struct mbuf *m)
{
u_int pktlen;
if ((m->m_flags & M_PKTHDR) != 0)
return m->m_pkthdr.len;
pktlen = 0;
while (m != NULL) {
pktlen += m->m_len;
m = m->m_next;
}
return pktlen;
}
To be honest I'm not sure if that makes a difference for the code generated
by GCC. But it might speed up compilation a bit.
Kind regards
