No, the ability to put a system call into a module is not allowed currently both by the existing design of the kernel, and because Linus does not want this to happen. You can have a syscall call into your module if it is present, if you register your module with the core after it is loaded. The LSM patch (at http://lsm.immunix.org/ ) does this if you want an example. thanks, greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
