The enum __ptrace_request is used to describe the function prototype in
the ptrace() manual page so one can argue that it's part of the official
API.

If I remeber right, it's missing in musl libc and the code in question
fails to compile.

CCing glibc ML and also man-pages ML to see if the type is used in
manual page intentionally or not.
