3.8. Using debugfs
The
debugfs
file system is specially designed for debugging and making information available to users. It must be mounted for use with ftrace
and trace-cmd
, and it is mounted automatically in Red Hat Enterprise Linux 7 under the /sys/kernel/debug/
directory.
You can verify that
debugfs
is mounted by running the following command:
~]# mount | grep ^debugfs
