Pull block stacking updates from Jens Axboe:
 "The stacking related fixes depended on both the core block and drivers
  branches, so here's a topic branch with that change.

  Outside of that, a late fix from Johannes for zone revalidation"

* tag 'for-5.9/block-merge-20200804' of git://git.kernel.dk/linux-block:
  block: don't do revalidate zones on invalid devices
  block: remove blk_queue_stack_limits
  block: remove bdev_stack_limits
  block: inherit the zoned characteristics in blk_stack_limits
