| 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. |
