  Modified files:
    sys/kern             kern_lock.c 
  Log:
  When requesting an exclusive lock with LK_NOWAIT, do not panic
  if LK_RECURSIVE is not set, as we will simply return that the
  lock is busy and not actually deadlock. This allows processes
  to use polling locks against buffers that they may already
  hold exclusively locked.
