What tends to happen is that kernel is changed to implement the old syscall using the new infrastructure on the kernel side. There's no real cost to having another syscall number used.
- Someone 8y agoBut it grows the amount of code in the kernel, making it more likely to be buggy, more so if some of these old interfaces get used less and less (and, hence, likely tested less and less), and the underlying root interface gets refactored again and again to support new polling interfaces.
- caf 8y agoWe are generally talking about very simple wrapper functions here that don't have a lot of scope for hidden bugs to creep in.
