Actually, the padlock driver shows the same 
behaviour.  Over time, its usage continues to grow

          Type InUse MemUse HighUse Requests  Size(s)
  padlock_data  4048  4048K       -     4048  1024

          Type InUse MemUse HighUse Requests  Size(s)
  padlock_data  4056  4056K       -     4056  1024

Or am I reading vmstat wrong ?
