I have downloaded new code from here(https://backports.wiki.kernel.org/index.php/Releases). Now after extracting the downloaded code, I am suppose to replace my old code files with the new one and then finally build it(That's what I know).
Now the issue is after I replaced my older files (c files and header files only) with the newer files there is #include_next preprocessor directive which gives me compilation error. I don't know what changes should I add to the existing makefile files[could not replace these older makefile with newer one because older one's are used to build the kernel] from the makefiles available here(https://backports.wiki.kernel.org/index.php/Releases) to build code successfully.
Please let me know if anyone wants more clearance on this.
Thank you
