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. * 'for-linus' of git://git.kernel.dk/linux-block: block: don't try to discard from __blkdev_issue_zeroout sd: remove __data_len hack for WRITE SAME nvme: use blk_rq_payload_bytes scsi: use blk_rq_payload_bytes block: add blk_rq_payload_bytes block: Rename blk_queue_zone_size and bdev_zone_size nvme: apply DELAY_BEFORE_CHK_RDY quirk at probe time too nvme-rdma: fix nvme_rdma_queue_is_ready virtio_blk: fix panic in initialization error path nbd: blk_mq_init_queue returns an error code on failure, not NULL virtio_blk: avoid DMA to stack for the sense buffer do_direct_IO: Use inode->i_blkbits to compute block count to be cleaned
