From riel@redhat.com Tue Dec 18 13:20:56 2007 Date: Tue, 18 Dec 2007 16:15:50 -0500 From: Rik van Riel To: linux-mm@kvack.org Cc: linux-kernel@vger.kernel.org, lee.shermerhorn@hp.com Subject: [patch 11/20] add newly swapped in pages to the inactive list Swapin_readahead can read in a lot of data that the processes in memory never need. Adding swap cache pages to the inactive list prevents them from putting too much pressure on the working set. This has the potential to help the programs that are already in memory, but it could also be a disadvantage to processes that are trying to get swapped in. In short, this patch needs testing.
