I'd like to add a feature request, understanding fully that the response may very 
well be, "interesting idea, now show us a patch"--can we have an interface that 
would allow kernel-space allocation of watchpoint registers?
The rationale is that we have found it quite useful to have kernel and driver 
code set watchpoints for debugging purposes. I would not expect that kernel space 
code could grab watchpoint registers already in use by ptrace, and that ptrace 
would be free to allocate all watchpoint registers not in use for kernel space 
purposes, i.e. there would be no watchpoint registers permanently allocated for 
kernel space usage.
