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

Pull block fixes from Jens Axboe:
 "A small set of fixes that should go into this release. This contains:

   - An NVMe pull request from Christoph, with a few select fixes.

     One of them fix a polling regression in this series, in which it's
     trivial to cause the kernel to disable most of the hardware queue
     interrupts.

   - Fixup for a blk-mq queue usage imbalance on request allocation,
     from Keith.

   - A xen block pull request from Konrad, fixing two issues with
     xen/xen-blkfront"
