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

Pull block layer fixes from Jens Axboe:
 "A couple of last minute fixes for regressions in this cycle. More
  specifically:

   - Two patches from Andy, adjusting the NVMe APST quirks to avoid some
     issues specific to one Toshiba drive, and some variant of Samsung
     on two specific Dell laptops.

   - A fix for mtip32xx, turning off mq scheduling on that device. We
     have a real fix for this, but it's too late in the cycle.
     Thankfully we already have a NO_SCHED flag we can apply here. A
     prep patch for this is ensuring that we honor the NO_SCHED flag
     when attempting to online switch schedulers, previsouly we only did
     so for drive load time. From Ming.

   - Fixing an oops in blk-mq polling with scheduling attached. This one
     is easily reproducible, it would be a shame to release 4.11 with
     that issue. From me.

  I'd prefer not having to send in patches at this point in time, but
  the above are all things that have regressed in this cycle and the
  fixes are relatively straight forward"
