384 If admin wants to use incompressible page writeback, they could do it via::
386 echo huge > /sys/block/zramX/writeback
388 Admin can request writeback of idle pages at right timing via::
390 echo idle > /sys/block/zramX/writeback
392 With the command, zram will writeback idle pages from memory to the storage.
