16 Description:
17                 The file /sys/devices/system/memory/memoryX/removable
18                 indicates whether this memory block is removable or not.
19                 This is useful for a user-level agent to determine
20                 identify removable sections of the memory before attempting
21                 potentially expensive hot-remove memory operation
