Bug Description

The xb_incremental test does not test the data file scanning for the updated pages.

A sample run of the test would result in the full backup done up to LSN 45342. Even though after the full backup completes there is a workload on the server, it apparently does not force the server to checkpoint.

Thus when the incremental backup is started, the only action required for the backup is log scanning from LSN 45342 to 202964.

Another confirmation is that tracing code added to the code path of page with LSN > incremental_lsn never triggers on 2.0 and 2.1.

The test needs to be updated so that workload between the backups makes InnoDB checkpoints.
