The patch titled vmscan: evict streaming IO first has been removed from the -mm tree. Its filename was vmscan-evict-streaming-io-first.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: vmscan: evict streaming IO first From: Rik van Riel <riel@xxxxxxxxxx> Count the insertion of new pages in the statistics used to drive the pageout scanning code. This should help the kernel quickly evict streaming file IO. We count on the fact that new file pages start on the inactive file LRU and new anonymous pages start on the active anon list. This means streaming file IO will increment the recent scanned file statistic, while leaving the recent rotated file statistic alone, driving pageout scanning to the file LRUs. Pageout activity does its own list manipulation.
