[v6 3/3] device-dax: "Hotremove" persistent memory that is used like normal RAM

2019-05-17 Thread Pavel Tatashin
It is now allowed to use persistent memory like a regular RAM, but currently there is no way to remove this memory until machine is rebooted. This work expands the functionality to also allows hotremoving previously hotplugged persistent memory, and recover the device for use for other purposes.
