Component Type: kbuild config

Description: Write back incompressible or idle page to backing device

More info: With incompressible page, there is no memory saving to keep it in memory. Instead, write it out to backing device. For this feature, admin should set up backing device via /sys/block/zramX/backing_dev. With /sys/block/zramX/{idle,writeback}, application could ask idle page's writeback to the backing device to save in memory. See Documentation/admin-guide/blockdev/zram.rst for more information.
