Merge tag 'for-linus-20180608' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "A few fixes for this merge window, where some of them should go in
  sooner rather than later, hence a new pull this week. This pull
  request contains:

   - Set of NVMe fixes, mostly follow up cleanups/fixes to the queue
     changes, but also teardown/removal and misc changes (Christop/Dan/
     Johannes/Sagi/Steve).

   - Two lightnvm fixes for issues that showed up in this window
     (Colin/Wei).

   - Failfast/driver flags inheritance for flush requests (Hannes).

   - The md device put sanitization and fix (Kent).

   - dm bio_set inheritance fix (me).

   - nbd discard granularity fix (Josef).

   - nbd consistency in command printing (Kevin).

   - Loop recursion validation fix (Ted).

   - Partition overlap check (Wang)"

[ .. and now my build is warning-free again thanks to the md fix  - Linus ]
