It's for the series of patches linked from http://lwn.net/Articles/259841/ If you do the renaming now, then when those get merged you can just remove the whole bunch of code for PTRACE_SINGLESTEP et al and call ptrace_request. (And yes, it will also leave things clean and ready for something new akin to utrace to come along later without your having to do anything more about it.)
