Current nvme driver in Ubuntu 16.04 kernel does not handle error recovery; we
are missing some patches from the upstream nvme driver.
We would like to ask Canonical to cherry pick the following patches for the
16.04 kernel, if possible:
* 9396dec916c0 ("nvme: use a work item to submit async event requests")
* 79f2b358c9ba ("nvme: don't poll the CQ from the kthread")
* 2d55cd5f511d ("nvme: replace the kthread with a per-device watchdog
timer")
* 9bf2b972afea ("NVMe: Fix reset/remove race")
* c875a7093f04 ("nvme: Avoid reset work on watchdog timer function during
error recovery")
* a5229050b69c ("NVMe: Always use MSI/MSI-x interrupts")
