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

Pull block fixes from Jens Axboe:
 "Small collection of fixes that would be nice to have in -rc1. This
  contains:

   - NVMe pull request form Christoph, mostly with fixes for nvme-pci,
     host memory buffer in particular.

   - Error handling fixup for cgwb_create(), in case allocation of 'wb'
     fails. From Christophe Jaillet.

   - Ensure that trace_block_getrq() gets the 'dev' in an appropriate
     fashion, to avoid a potential NULL deref. From Greg Thelen.

   - Regression fix for dm-mq with blk-mq, fixing a problem with
     stacking IO schedulers. From me.

   - string.h fixup, fixing an issue with memcpy_and_pad(). This
     original change came in through an NVMe dependency, which is why
     I'm including it here. From Martin Wilck.

   - Fix potential int overflow in __blkdev_sectors_to_bio_pages(), from
     Mikulas.

   - MBR enable fix for sed-opal, from Scott"
