[PATCH 0/4v3] nvme-fc: track state change failures

[hare@suse.de (Hannes Reinecke)]

Hi all,

this patchset improves logging in the nvme-fc driver if expcected
state changes fail, and fixes up one case where a failed state change
might lead to a stuck controller.

Changes to v2:
- Tear down association on failure as suggested by James Smart
- Align nvme_fc_delete_association() with the exit path
Changes to v1:
- simplified accessor function as suggested by Minwoo Im
- Included suggestions from James Smart

Hannes Reinecke (4):
  nvme: separate out nvme_ctrl_state_name()
  nvme-fc: track state change failures during reconnect
  nvme-fc: fail reconnect if state change fails
  nvme-fc: align nvme_fc_delete_association() with exit path
