Subject: [RFC][PATCH 0/7] low latency synchrounous lumpy reclaim


If slow usb storage is connected and run plenty io operation, lumpy
reclaim often stall in shrink_inactive_list(). This patch series try 
to solve this issue.
At least, This works fine on my desktop and usb stick environment :-)

This patch is still RFC. comment, reviewing and testing are welcome!




Wu Fengguang (1):
  vmscan: raise the bar to PAGEOUT_IO_SYNC stalls

KOSAKI Motohiro (6):
  vmscan: synchronous lumpy reclaim don't call congestion_wait()
  vmscan: synchrounous lumpy reclaim use lock_page() instead trylock_page()
  vmscan: narrowing synchrounous lumply reclaim condition
  vmscan: kill dead code in shrink_inactive_list()
  vmscan: remove PF_SWAPWRITE from __zone_reclaim()
  vmscan: isolated_lru_pages() stop neighbor search if neighbor can't be isolated
