  [PATCH] Kenneth Sumrall: In lp_write(), copy_from_user() is called to copy data into a statically allocated kernel buffer before down_interruptible().
  
  From: Kenneth Sumrall <ken@mvista.com>
  
  In lp_write(), copy_from_user() is called to copy data into a statically
  allocated kernel buffer before down_interruptible() is called.  If a second
  thread of execution comes in between the copy_from_user() and the
  down_interruptible() calls, silent data corruption could result.
