NVME hotplug support ?

[Damien Hedde]

Hi all,

We are currently looking into hotplugging nvme devices and it is currently not 
possible:
When nvme was introduced 2 years ago, the feature was disabled.

Do someone know what's lacking or anyone have some tips/idea of what we should 
develop to add the support ?
