[petsc-users] Strange compiling error in DMPlexDistribute after updating PETSc to V3.11.0

[Balay, Satish]

A fortran interface definition was added in petsc-3.11 so the compile now checks if its used correctly.

http://bitbucket.org/petsc/petsc/commits/fdb49207a8b58c421782c7e45b1394c0a6567048

+          PetscSF, intent(out) :: sf

So this should be inout?

[All auto-generated stubs don't quantify intent()]
