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.Annotation

- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
