289 6.1 Memory offline and ZONE_MOVABLE
291 Memory offlining is more complicated than memory online. Because memory offline
292 has to make the whole memory block be unused, memory offline can fail if

316   Size of memory for movable pages (for offline) is TOTAL-YYYY.
319   Size of memory not for movable pages (not for offline) is TOTAL - ZZZZ.
320   Size of memory for movable pages (for offline) is ZZZZ.
327 6.2. How to offline memory
329 You can offline a memory block by using the same sysfs interface that was used
332 % echo offline > /sys/devices/system/memory/memoryXXX/state
334 If offline succeeds, the state of the memory block is changed to be "offline".
336 Even if a memory block does not belong to ZONE_MOVABLE, you can try to offline
