John,
You mentioned that the Ori Pomerantz's LKM Programming Guide is too old
for /proc part. Does this also apply to Chapter 7 System Calls? I
want to add a system call, say nrprocess(), with these steps: 1) add an
entry in include/asm-i386/unistd.h 2) #insmod nrprocess.o
but I don't see how the userland application know the new system call.
Do I have to recompile the kernel? I wonder there is document which
explains that.
Thanks for the help,
-Hong
