From fa30bd058b746c0e2318a77ff8b4977faa924c2c Mon Sep 17 00:00:00 2001 From: Badari Pulavarty Date: Sun, 26 Mar 2006 01:38:01 -0800 Subject: [PATCH] map multiple blocks for mpage_readpages() This patch changes mpage_readpages() and get_block() to get the disk mapping information for multiple blocks at the same time. b_size represents the amount of disk mapping that needs to mapped. On the successful get_block() b_size indicates the amount of disk mapping thats actually mapped. Only the filesystems who care to use this information and provide multiple disk blocks at a time can choose to do so. No changes are needed for the filesystems who wants to ignore this.
