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

Pull block fixes from Jens Axboe:

 - the virtio_blk stack DMA corruption fix from Christoph, fixing and
   issue with VMAP stacks.

 - O_DIRECT blkbits calculation fix from Chandan.

 - discard regression fix from Christoph.

 - queue init error handling fixes for nbd and virtio_blk, from Omar and
   Jeff.

 - two small nvme fixes, from Christoph and Guilherme.

 - rename of blk_queue_zone_size and bdev_zone_size to _sectors instead,
   to more closely follow what we do in other places in the block layer.
   This interface is new for this series, so let's get the naming right
   before releasing a kernel with this feature. From Damien.
