Is Documentation/ioctl-numbers.txt still accurate?

File Documentation/ioctl-numbers.txt documents the IOCTL "magic" numbers already
in use by the 2.1.15 kernel (that's 15, not 115). This brings to mind 2
questions:

1. How accurate is this document today? A whole lotta changes have been made to
the kernel in the 7 months since this document was written. Am I really on safe
ground if I choose a number not listed as already being in use?

2. Is there a way (other than trial-and-error) to determine if a given "magic"
number is already in use by the kernel?

Thank you.
