I don't actually know, my initial interpretation was that these function names are part of the user ABI for the vdso, but I never looked closely enough at how vdso works to be sure what the actual ABI is. If __c_kernel_clock_gettime() etc are not part of the user-facing ABI, I think renaming them for consistency with the other architectures would be best. Arnd
