In particular daxctl_memory_op(), used to implement stuff like

daxctl online-memory
daxctl offline-memory
daxctl reconfigure-device (--no-online, --no-movable)


I am not sure if they also offline memory automatically before disabling 
a device.

But in essence, they want to to everything automatically as possible.
