Log:
  MFC r197518:
  
    lindev(4) [1] is supposed to be a collection of linux-specific pseudo
    devices that we also support, just not by default (thus only LINT or
    module builds by default).
  
    While currently there is only "/dev/full" [2], we are planning to see more
    in the future.  We may decide to change the module/dependency logic in the
    future should the list grow too long.
  
    This is not part of linux.ko as also non-linux binaries like kFreeBSD
    userland or ports can make use of this as well.
