unimplemented syscalls
 

hi
can any one say some unimplemented syscalls which are not used like thread_size which i can include in kernel/sys.c.
thank you in advance

looking through syscall numbers
 

Generally, cat linux-2.6/arch/x86/kernel/syscall_table_32.S and this shows a list of the Linux system calls. System call numbers whose element in the table point to sys_ni_syscall are not in use generally, though the comment to the right gives some context. You can get a copy of the kernel sources from kernel.org.
