selva:
After adding a new system call, should we have to
recompile the whole kernel? can anyone help me
regarding this?
Thanks
selva

Yes, it's expected that you rebuild the kernel
(at least all affected files), then reboot that
kernel to use the new syscall.
OTOH, there has been some recent email on lkml about
dynamic syscalls and a way to allow them (mostly for
experimental use AIUI, but if that's the case, just
rebuilding and rebooting would probably do for most
people).

You do not need to do a 'make clean'. Simply executing make will suffer
since kbuild has track of all dependencies.
Assuming 2.6 kernel!

Even in 2.4 you do not need make clean. make dep should suffice if you changed
some includes.
I dislike how many FAQs and tutorials always add "do a make clean"... that
requires you to recompile everything (read: may take "some time", when in
practice you only need a few things (i'm speaking generally, any app is
considered).
