H A Dzram.rst309 writeback section in Optional Feature
319 If admin wants to use incompressible page writeback, they could do it via::
321 echo huge > /sys/block/zramX/writeback
323 To use idle page writeback, first, user need to declare zram pages
340 Admin can request writeback of those idle pages at right timing via::
342 echo idle > /sys/block/zramX/writeback
344 With the command, zram will writeback idle pages from memory to the storage.
346 Additionally, if a user choose to writeback only huge and idle pages
349 echo huge_idle > /sys/block/zramX/writeback
