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

Pull block revert from Jens Axboe:
 "The previous pull request had a split fix for NVMe, however there are
  corner cases where that ends up blowing up.

  So let's revert it for 4.4.  The regression isn't introduced in this
  cycle, and it's "just" a performance regression, not a
  stability/integrity issue"

* 'for-linus' of git://git.kernel.dk/linux-block:
