This driver can be loaded as an overlay on top of a real block device, and can then be used to generate block-level failures for certain transfer requests. Specifically, a rule-based system allows the user to introduce (overt and silent) data corruption and errors. It exposes itself through /dev/fbd, and a file system can be mounted on top of it. The new fbdctl(8) tool can be used to control the driver; see ``man fbdctl'' for details. It also comes with a test set, located in test/fbdtest.
