I am very new to this kernel thing. What I want to do is just add a new system call to the kernel. I was following this guideline: http://hekimian-williams.com/?p=20.
The problem is there used to syscall_table_32.S file under arch/x86/kernel, but I cannot find the file for x86 systems in kernel version 3.3. Do I still need to edit the file and append one more line for the newly added system call? Or do I need to do something else to let the kernel know about my new system call? Any help will be appreciated. Thank you.
I think in kernel 3.3 its shifted here
