[PATCH v2 0/2] block: Fix a race between the throttling code and request queue initialization

Hello Jens,

The two patches in this series fix a recently reported race between the
throttling code and request queue initialization. It would be appreciated
if you could have a look at this patch series.

Thanks,

Bart.

Changes between v1 and v2:
- Split a single patch into two patches.
- Dropped blk_alloc_queue_node2() and modified all block drivers that call
  blk_alloc_queue_node().

Bart Van Assche (2):
  block: Add a third argument to blk_alloc_queue_node()
  block: Fix a race between the throttling code and request queue
    initialization
