Gluten implemented some logic to convert call expr as subfield filter. To avoid duplication, we would like to use the existing 'leafCallToSubfieldFilter' logic in Velox. One incompatibility we found is current implementation is matching against Presto function names, while Spark function names could be different. The other one is 'isnotnull' is frequently used in Spark and it is not currently supported. These are the drafted changes we would like to propose: rui-mo@7340903.
