  Modified files:
    share/man/man9       bus_dma.9 
  Log:
  Clarify what the lockfunc is used for.  When it will be called and
  when it won't be called.  The old wording was correct, but not
  sufficiently specific to understand when and how it would be called.
  The new wording describes the current implementation's usage (which
  should be updated if other appropriate times are decided upon),
  specifically that it is called only when the load operation is
  deferred to keep the locking state consistent.  When the operation
  isn't deferred, the calling routine is assumed to have a coherent
  locking world.
