|ksp||- the ksp context being used.|
|total_its||- the total number of FGMRES iterations that have occurred.|
|loc_its||- the number of FGMRES iterations since last restart. a restart (so number of Krylov directions to be computed)|
|res_norm||- the current residual norm.|
|dummy||- context variable, unused in this routine|
