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.
