Not sure if Ted is still interested in maintaining this file as he had no feedback for more
than a month. The problem is that this will render the lockdep useless for a general
debugging tool as it will disable the lockdep early in the process.

Could Andrew (since the free page shuffle will call get_random) or Linus pick this up
directly with the approval from one of the printk() maintainers above?
