      block: Initialize cfqq->ioprio_class in cfq_get_queue() · 4d608baa

      KMSAN (KernelMemorySanitizer, a new error detection tool) reports use of
      uninitialized memory in cfq_init_cfqq():

      (the line numbers are relative to 4.8-rc6, but the bug persists
      upstream)
      
      The uninitialized struct cfq_queue is created by kmem_cache_alloc_node()
      and then passed to cfq_init_cfqq(), which accesses cfqq->ioprio_class
      before it's initialized.

      blk-mq: allow resize of scheduler requests · 70f36b60
      Jens Axboe authored
      Add support for growing the tags associated with a hardware queue, for
      the scheduler tags. Currently we only support resizing within the
      limits of the original depth, change that so we can grow it as well by
      allocating and replacing the existing scheduler tag set.
      
      This is similar to how we could increase the software queue depth with
      the legacy IO stack and schedulers.

      Merge tag 'usb-4.10-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb · 83280e90
      Linus Torvalds authored
      Pull USB fixes from Greg KH:
       "Here are a bunch of USB fixes for 4.10-rc3. Yeah, it's a lot, an
        artifact of the holiday break I think.
      
        Lots of gadget and the usual XHCI fixups for reported issues (one day
        that driver will calm down...) Also included are a bunch of usb-serial
        driver fixes, and for good measure, a number of much-reported MUSB
        driver issues have finally been resolved.
      
        All of these have been in linux-next with no reported issues"
