From 6798d35a31c413bbb3f83bbaa844bd2598168ccc Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 7 Sep 2007 14:05:51 -0700 Subject: ocfs2: Read support for inline data This hooks up ocfs2_readpage() to populate a page with data from an inode block. Direct IO reads from inline data are modified to fall back to buffered I/O. Appropriate checks are also placed in the extent map code to avoid reading an extent list when inline data might be stored.
