    Robert Richter authored
    This patch restores default values for:
    
    /dev/oprofile/cpu_buffer_size
    /dev/oprofile/buffer_watershed
    /dev/oprofile/buffer_size
    
    when creating the oprofilefs:
    
     # opcontrol --deinit
     # opcontrol --init
     # cat /dev/oprofile/cpu_buffer_size
     8192
     # echo 5123 > /dev/oprofile/cpu_buffer_size
     # cat /dev/oprofile/cpu_buffer_size
     5123
     # opcontrol --deinit
     # opcontrol --init
     # cat /dev/oprofile/cpu_buffer_size
     8192
     # opcontrol --deinit
    
    This sets the values in a defined state. Before, there was no way to
    restore the defaults without rebooting the system or reloading the
    module.
