That is upto the caller. returning 0 for an operation we were supposed
to do, but due to error checks, did not do, implies we need to provide
appropriate error back to caller. caller may choose to act upon the
error and do something OR not - depending on what the caller is (for
example, caller may choose to abort the full sequence as it does not
trust the entries anymore, OR maybe trying to add optional OPP - whose
failure is ignored) - it is NOT upto the this code to implement that
policy.
