==================
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
+ call. It can check if file handles are valid or stale after certain
+ filesystem operations.

+ _require_exportfs
+
stat_test
The stat_test program is primarily designed to exercise the statx()
_require_statx
+t_dir_type
+
+ The t_dir_type program exercises the getdents64() system call.
+ It prints directory entry names returned from getdents64() and
+ thier d_type, optionally filtered by type or by inode number.
+
xfs_io
The xfs_io program can be found in the xfsprogs package and can be used
