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

Pull block fixes from Jens Axboe:
 "A few fixes that should go into this series:

   - Regression fix for ide-cd, ensuring that a request is fully
     initialized. From Hongxu.

   - Ditto fix for virtio_blk, from Bart.

   - NVMe fix from Keith, ensuring that we set the right block size on
     revalidation. If the block size changed, we'd be in trouble without
     it.

   - NVMe rdma fix from Sagi, fixing a potential hang while the
     controller is being removed"

* 'for-linus' of git://git.kernel.dk/linux-block:
  ide:ide-cd: fix kernel panic resulting from missing scsi_req_init
  nvme: Fix setting logical block format when revalidating
  virtio_blk: Fix an SG_IO regression
  nvme-rdma: fix possible hang when issuing commands during ctrl removal
