bool "Write back incompressible or idle page to backing device"
depends on ZRAM
help
- With incompressible page, there is no memory saving to keep it
- in memory. Instead, write it out to backing device.
+ This lets zram entries (incompressible or idle pages) be written
+ back to a backing device, helping save memory.
For this feature, admin should set up backing device via
/sys/block/zramX/backing_dev.
