Subject: Re: [RFC][v7][PATCH 8/9]: Define clone2() syscall

The glibc prototype for clone uses ... and is not a direct map to the
syscall args anyway.  So that would not change for adding more optional
args enabled by certain flags, as it did not change to add the tid pointer
arguments before.  But indeed the library function would have to change to
pass on additional or different args to the existing syscall.


Thanks,
Roland
