 This is the maximum amount of memory which the zram device can use.
 Setting it to '0' disables the limit.  While it is generally expected
 that compression will be 2:1, it is possible that uncompressable data
 can be written to swap and this is a method to limit how much memory can
 be used.  It accepts a string and can be a number of bytes or use a
