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.
What: /sys/kernel/mm/swap/vma_ra_max_order
Date: August 2017
Contact: Linux memory management mailing list <linux-mm@kvack.org>
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.
