[PATCH V3 0/6] blk-mq: update_nr_hw_queues related improvement & bugfix

[Ming Lei <ming.lei@redhat.com>]

Hi,

The 1st patch figures out correct numa node for each kind of hw queue.

The 2nd patch simplifies reallocation of q->queue_hw_ctx a bit.

The 3rd patch re-configures poll capability after queue map is changed.

The 4th patch changes mtip32xx to avoid to refer to q->queue_hw_ctx
directly.

The 5th & 6th patches fix use-after-free on q->queue_hw_ctx.

V3:
	- fix smatch warnings reported by kernel test robot (5/6)

V2:
	- use xa_for_each() to implement queue_for_each_hw_ctx(5/6 6/6) 
	- patch style change(1/6)
	- rename as suggested by Christoph(3/6)
