[PATCH RFC 0/4] Move active IO termination to the core

[Sagi Grimberg]

This patchset adds helper to active IO termination to the nvme
core based on the pci nvme_clear_queues() functionality. This
is needed for live shutdowns and resets during live IO and it's
not pci specific and will be needed for other transports as well.

Sagi Grimberg (4):
  blk-mq: Export tagset iter function
  nvme: Add a controller reference to the admin tagset
  nvme: Move IO termination code to the core
  blk-mq: Make blk_mq_all_tag_busy_iter static
