//
//  The following two procedures are used by the Fsd/Fsp exception handlers to
//  process an exception.  The first macro is the exception filter used in the
//  Fsd/Fsp to decide if an exception should be handled at this level.
//  The second macro decides if the exception is to be finished off by
//  completing the IRP, and cleaning up the Irp Context, or if we should
//  bugcheck.  Exception values such as STATUS_FILE_INVALID (raised by
//  RdrIsOperationValid) cause us to complete the Irp and cleanup, while
//  exceptions such as access violation cause us to bugcheck.
//
//  The basic structure for fsd/fsp exception handling is as follows:
//
//  RdrFsdXxx(...)
//  {
//      try {
//          NTSTATUS Status;
//          ...
//
