If you can not compile that sources, than you should not use kevent for
a while. Definitely.
Options are pretty simple: -W -Wall -I$(path_to_kernel_tree)/include

So what?
People bring me tons of various stuff, and I prefer to use my own for
tests. If _you_ need it, _you_ can always patch any sources you like.

You missed the point - I'm not going to patch tons of existing
applications when I'm asked to change an interface once per month.
When all requested features are implemented I definitely with patch some
popular web-server to show how kevent is used.

And? Please provide a link to archive.

:)) i.e. it is ok for you to 'read some books on TCP/IP and Ethernet' to
understand how utility works, and it is not ok to determine how to
compile my sources? Do not compile my sources.

And why lighttpd still do not use it?
You should start to blame authors of the splice() for that.
You will not? Then I can not consider your words in my direction as
serious.

You do not use kevent, why do you care about indent of the userspace

This thread is just to answer for the sake of answers - there is
completely no sense in it.
You blame me that I did not create some benchmarks you like, but I do not
care about it. I created usefull patch and test is in the way I like,
because it is much more productive, than spending a lot of time
detemining how different sources work with appropriate loads.
When there will be strong requirement to perform additional tests, I
will do them.
