    Subject[PATCH 04/16] dynamic_debug: change verbosity at runtime
    From: Jim Cromie <jim.cromie@gmail.com>

    Allow changing dynamic_debug verbosity at run-time, to ease debugging
    of ddebug queries as you add them, improving usability.

    at boot time: dynamic_debug.verbose=1
    at runtime:
    root@voyage:~# echo 1 > /sys/module/dynamic_debug/parameters/verbose
