From cf914a7d656e62b9dd3e0dffe4f62b953ae6048d Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 19 Jul 2007 01:48:08 -0700 Subject: readahead: split ondemand readahead interface into two functions Split ondemand readahead interface into two functions. I think this makes it a little clearer for non-readahead experts (like Rusty). Internally they both call ondemand_readahead(), but the page argument is changed to an obvious boolean flag.
