  37           Enabling this option turns a certain set of sanity checks for user
  38           copy operations into compile time failures.
  39
  40           The copy_from_user() etc checks are there to help test if there
  41           are sufficient security checks on the length argument of
  42           the copy operation, by having gcc prove that the argument is
  43           within bounds.
  44
  45           If unsure, or if you run an older (pre 4.4) gcc, say N.
