I like it. If your distro has some auto-onlining udev rule like
SUBSYSTEM=="memory", ACTION=="add", ATTR{state}=="offline", ATTR{state}="online"
You could get things onlined as movable just by putting movable_node in
the boot params, without changing/modifying the rule.
yes this is the primary point of the patch ;)
Ha. What can I say, I like restating the obvious!
At some point after all these cleanups/improvements, it would be worth
making sure Documentation/memory-hotplug.txt is still accurate.
