[PATCH v2 for-4.6 0/3] Provide better active I/O termination handlers

[Sagi Grimberg]

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

This patchset applies on top of "for-4.6-drivers" patchset.

Changes from v1:
- rebase on top of for-4.6-drivers (small fuzz)
- incorporate a fix from hch to carefully check for valid tagsets

Changes from v0:
- Removed the nvme core helpers for IO termination and have pci
  use blk-mq helper directly
- Rebased on top of Keith and Christoph's patches

Sagi Grimberg (3):
  blk-mq: Export tagset iter function
  nvme: Use blk-mq helper for IO termination
  blk-mq: Make blk_mq_all_tag_busy_iter static
