 	The af_unix program creates an AF_UNIX socket at the given location.
 
+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.
+
 open_by_handle
 
 	The open_by_handle program exercises the open_by_handle_at() system
