i'm wondering about swap-prefetch:

mm-implement-swap-prefetching.patch
swap-prefetch-avoid-repeating-entry.patch
add-__gfp_movable-for-callers-to-flag-allocations-from-high-memory-that-may-be-migrated-swap-prefetch.patch

The swap-prefetch feature is relatively compact:

10 files changed, 745 insertions(+), 1 deletion(-)

it is contained mostly to itself:

mm/swap_prefetch.c | 581 ++++++++++++++++++++++++++++++++

i've reviewed it once again and in the !CONFIG_SWAP_PREFETCH case it's a
clear NOP, while in the CONFIG_SWAP_PREFETCH=y case all the feedback
i've seen so far was positive. Time to have this upstream and time for a
desktop-oriented distro to pick it up.

I think this has been held back way too long. It's .config selectable
and it is as ready for integration as it ever is going to be. So it's a
win/win scenario.
