Hi Jens,

This patch series reduces the amount of memory required for request queues
and also includes a patche that is the result of reviewing code related
to the modified code. Please consider these patches for kernel version v5.5.

Thanks,

Bart.

Changes compared to v1:
- Dropped the blk_poll() patch from this series.

Bart Van Assche (3):
  block: Remove the synchronize_rcu() call from
    __blk_mq_update_nr_hw_queues()
  block: Reduce the amount of memory required per request queue
  block: Reduce the amount of memory used for tag sets
