I am not sure what the point of these is? The userspace visibility of the regular posix clocks (positive clockid's) does not change. The way we encode process cputime clocks as negative values changes but there is nothing that supports my encoding yet (apart from my test code) since the glibc patch was never accepted.
I would like to keep the support for all 4 standard posix clocks through clockids 0-3 as listed in the kernel headers and simply have the cputime clocks redirect to your code appropriately to get the current values for each process. IMHO that makes the interface cleaner, is cleaner for glibc since it allows simply to pass positive clockids through and also maintains compatibility for positive clockids to the existing situation.
