Hi all! I wrote a function under 2.4.4 which simply mimics the behaviour of tcp_sendmsg() but with zerocopy (uses do_tcp_send_pages()). I also added the function to the netsyms.c file & then compiled the kernel & booted from it. when I try to insmod a module which simply makes a call to my function, I get an unresolved symbol. help will be mostly appreciated.
