[petsc-users] Near nullspace lost in fieldsplit

[Jeremy Theler (External)]

Hi Barry

>   The bug fix for 2 is availabel in https://gitlab.com/petsc/petsc/-/merge_requests/7279

Note that our code goes through   MatZeroRowsColumns_MPIAIJ() not through MatZeroRows_MPIAIJ() so this fix does not change anything for the case I mentioned.
