Not likely my patches, they may cause regression only when there are
many VM_EXEC mapped pages.
You can try reverting this patch, it is a much bigger change for normal systems.
commit 56e49d218890f49b0057710a4b6fef31f5ffbfec

vmscan: evict use-once pages first
When the file LRU lists are dominated by streaming IO pages, evict those
pages first, before considering evicting other pages.
This should be safe from deadlocks or performance problems
because only three things can happen to an inactive file page:
1) referenced twice and promoted to the active list
2) evicted by the pageout code
3) under IO, after which it will get evicted or promoted
The pages freed in this way can either be reused for streaming IO, or
allocated for something else. If the pages are used for streaming IO,
this pageout pattern continues. Otherwise, we will fall back to the
normal pageout pattern.
Thanks,
Fengguang
