backward compatibility in kernels + custom kernels + more queries
 
hi,

the following site contains a project in linux which i wanna try out by compiling it into the kernel

http://www.cs.wisc.edu/~remzi/Classe...ianVenkat.html

the project has 6 files which are modified kernel files, hence it was necessary for me to find out the correct version of the kernel since the version used is not mentioned anywhere.the 6 files are:

buffer.c
exit.c
fork.c
sched.h
unistd.h
entry.S

now using diff command and the patch history at linuxhq.com and the lxr i finally zeroed on that the kernel version was 2.2.13.
i am however using fc-4 with an updated kernel of 2.6.17 and i want to compile this project and run it. however i seem to be getting errors at the make step:
Code:
make: *** [init/main.o] Error 1
now i have several questions:
*can i compile a 2.2.13 kernel on fc 4 with 2.6.17?
*can i have some kinda backward compatibility with any of the recent kernels to accommodate those 6 files?
*can someone tell me why i get that error?

thanks!

steve

the complete error
 
here is the complete error after the make command.

i did not receive any errors after the make config and the make dep commands
