[petsc-users] Are there any functions (objects ) for scattering and gathering 64-bit integers just like VecScatter for PetscScalar?

For the third time, look at the title of the issue I linked. I'm not going
to answer any more questions that are directly addressed in that issue

things done.

This is higher priority now because we are using PetscSF in some more
visible places.
