Subject: [patch 0/3] activate pages in batch
Date: Thu, 23 Oct 2008 00:50:06 +0200 [thread overview]
Message-ID: <20081022225006.010250557@saeurebad.de> (raw)
Instead of re-acquiring the highly contented LRU lock on every single
page activation, deploy an extra pagevec to do page activation in
batch.
The first patch is just grouping all pagevecs we use into one array
which makes further refactoring easier.
The second patch simplifies the interface for flushing a pagevec to
the proper LRU list.
And finally, the last patch changes page activation to batch-mode.
