vmscan: Do not writeback filesystem pages in direct reclaim
again, very sorry for the delay. When memory is under enough pressure, a process may enter direct reclaim to free pages in the same manner kswapd does. If a dirty page is encountered during the scan, this page is written to backing storage using mapping->writepage. This can result in very deep call stac... 5 Aug 2010 03:44

lockdep and oops_in_progress
Hi guys, I was debugging a wierd issue with suspend/resume and fbcon/X with some recent work Jesse and myself did to try and make sure a pinned fbcon always gets the text on it with a panic or oops occurs. It does this by testing the oops_in_progress flag, however once any lockdep issue occurs it looks to me t... 5 Aug 2010 11:20
[PATCH 7/7] vmscan: isolated_lru_pages() stop neighbor search if neighbor can't be isolated
isolate_lru_pages() doesn't only isolate LRU tail pages, but also isolate neighbor pages of the eviction page. Now, the neighbor search don't stop even if neighbors can't be isolated. It is silly. successful higher order allocation need full contenious memory, even though only one page reclaim failure mean to fai... 5 Aug 2010 02:40
[PATCH 4/7] vmscan: narrowing synchrounous lumply reclaim condition
Now, mainly shrink_page_list() give up to reclaim the page by following 10 reasons. 1. trylock_page() failure 2. page is unevictable 3. zone reclaim and page is mapped 4. PageWriteback() is true 5. page is swapbacked and swap is full 6. add_to_swap() failure 7. page is dirty and gfpmask don't ha... 5 Aug 2010 02:40
[PATCH 2/7] vmscan: synchronous lumpy reclaim don't call congestion_wait()
congestion_wait() mean "waiting quueue congestion is cleared". That said, if the system have plenty dirty pages and flusher thread push new request to IO queue conteniously, IO queue are not cleared congestion status for long time. thus, congestion_wait(HZ/10) become almostly equivalent schedule_timeout(HZ/10). ... 5 Aug 2010 02:40
