[PATCH 0/4] nvme: ANATT handling

[hare@suse.de (Hannes Reinecke)]

Hi all,

this patchset implements ANA transition timeout handling for NVMe-oF.
On the target side it implements a delayed workqueue for updating the
ANA state, and on the host side a simple timer is started when either
a namespace is found to be in ANA state change state or if an I/O
command is returned with a status indicating a non-matching ANA state.
If the timer expires the controller is reset.

Patches are relative to hchs block.git nvme-ana branch.

As usual, comments and reviews are welcome.

  nvme: start ANATT timer on out-of-order state changes
