The functionality is used by the kernel internally anyway so there is no point removing it as it has no cost at all. You can equally call "reboot" by mistake or strcpy with wrong parameters. The interface is also part of our historic ABI/API so shouldn't just get booted out. You might not like it, and it might not be very useful but thats true of stuff like readahead() as well. Alan
