Hi Jens,

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

Thanks,

Bart.

Bart Van Assche (4):
  block: Remove the synchronize_rcu() call from
    __blk_mq_update_nr_hw_queues()
  block: Fix a race between blk_poll() and 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
