From 15b1e36bdb487d67ef924a37b0967453143be53a Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Fri, 7 Sep 2007 13:58:15 -0700 Subject: ocfs2: Structure updates for inline data Add the disk, network and memory structures needed to support data in inode. Struct ocfs2_inline_data is defined and embedded in ocfs2_dinode for storing inline data. A new inode field, i_dyn_features, is added to facilitate tracking of dynamic inode state. Since it will be used often, we want to mirror it on ocfs2_inode_info, and transfer it via the meta data lvb.
