Summary

struct tcpcb embeds a struct osd and a struct callout. Rather than
forcing all consumers to pull in the same
headers, include the headers directly.

No functional change intended.

There is a guard at line 88:

#if defined(_KERNEL) || defined(_WANT_TCPCB)

Maybe move the includes there, just next to netinet/cc/cc.h?
What's the final goal of the change?

Include headers only when needed.

Thanks, I missed that. Done.

What's the final goal of the change?

In general we've been trying to make kernel headers self-contained when possible. In my case I found some bits in net-snmp which do not compile because these includes are missing.

I'm fine with this change, but I really prefer net-snmp not to know anything about struct tcpcb. I'll take a look at it later.
