-It is also possible to deactivate the debug feature globally for every
-debug log. You can change the behavior using  2 sysctl parameters in
-/proc/sys/s390dbf:
-There are currently 2 possible triggers, which stop the  debug feature
-globally. The first possbility is to use the "debug_active" sysctl. If
-set to 1 the debug feature is running. If "debug_active" is set to 0 the
-debug feature is turned off.
-The second trigger which stops the debug feature is an kernel oops.
-That prevents the debug feature from overwriting debug information that
-happened before the oops. After an oops you can reactivate the debug feature
-by piping 1 to /proc/sys/s390dbf/debug_active. Nevertheless, its not
-suggested to use an oopsed kernel in an production environment.
-If you want to disallow the deactivation of the debug feature, you can use
-the "debug_stoppable" sysctl. If you set "debug_stoppable" to 0 the debug
-feature cannot be stopped. If the debug feature is already stopped, it
-will stay deactivated.
