Merge branch 'for-4.5/lightnvm' of git://git.kernel.dk/linux-block

Pull lightnvm fixes and updates from Jens Axboe:
 "This should have been part of the drivers branch, but it arrived a bit
  late and wasn't based on the official core block driver branch.  So
  they got a small scolding, but got a pass since it's still new.  Hence
  it's in a separate branch.

  This is mostly pure fixes, contained to lightnvm/, and minor feature
  additions"
