+dmerror
+
+       dmerror is a program for creating, destroying and controlling a
+       fault injection device. The device can be set up as initially
+       working and then flip to throwing errors for testing purposes.
+
+fsync-err
+
+       Specialized program for testing how the kernel reports errors that
+       occur during writeback. Works in conjunction with the dmerror script
+       in tools/ to write data to a device, and then force it to fail
+       writeback and test that errors are reported during fsync and cleared
+       afterward.
+
+log-writes/replay-log
+
+       Specialized program for replaying a write log that was recorded by
+       device mapper log-writes target.  The tools is used to perform crash
+       consistency tests, allowing to run an arbitrary check tool (fsck) at
+       specified checkpoints in the write log.
