Merge tag 'for-linus-20180629' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "Small set of fixes for this series. Mostly just minor fixes, the only
  oddball in here is the sg change.

  The sg change came out of the stall fix for NVMe, where we added a
  mempool and limited us to a single page allocation. CONFIG_SG_DEBUG
  sort-of ruins that, since we'd need to account for that. That's
  actually a generic problem, since lots of drivers need to allocate SG
  lists. So this just removes support for CONFIG_SG_DEBUG, which I added
  back in 2007 and to my knowledge it was never useful.

  Anyway, outside of that, this pull contains:

   - clone of request with special payload fix (Bart)

   - drbd discard handling fix (Bart)

   - SATA blk-mq stall fix (me)

   - chunk size fix (Keith)

   - double free nvme rdma fix (Sagi)"
