1. Don't do this.
2. Don't do this, unless you really know what you're doing.
3. If you want to do it anyway, take a look at my cowlink patches:

Very interesting patches,but what i need to is a pacth or some points so i
can change the existing source code according to my needs.Can someone help
me on that?
The existing sendfile system call copies data from a file descriptor to a
socket descriptor.I have already a program that i have to port that uses
the sendfile syscall from 2.4.x series kernels.In 2.6.x doesnt work.What
are the minimal changes that have to be done so i can use again the
syscall in 2.6.x kernel's???


Thanks in advance.

The first two patches (generic_sendpage.patch and sendfile.patch)
should be all you need.  But they were rather quick hack and I haven't
seriously looked at them for quite a while.

Maybe I should change that.  Several people appear to be generally
interested in the subject.
