| Description: Enable/disable VMA based swap readahead. |
| |
| If set to true, the VMA based swap readahead algorithm |
| will be used for swappable anonymous pages mapped in a |
| VMA, and the global swap readahead algorithm will be |
| still used for tmpfs etc. other users. If set to |
| false, the global swap readahead algorithm will be |
| used for all swappable pages. |

| Description: The max readahead size in order for VMA based swap readahead |
| |
| VMA based swap readahead algorithm will readahead at |
| most 1 << max_order pages for each readahead. The |
| real readahead size for each readahead will be scaled |
| according to the estimation algorithm. |
