From dcd0538ff4e854fa9d7f4630b359ca8fdb5cb5a8 Mon Sep 17 00:00:00 2001 From: Mark Fasheh Date: Tue, 16 Jan 2007 11:32:23 -0800 Subject: ocfs2: sparse b-tree support Introduce tree rotations into the b-tree code. This will allow ocfs2 to support sparse files. Much of the added code is designed to be generic (in the ocfs2 sense) so that it can later be re-used to implement large extended attributes. This patch only adds the rotation code and does minimal updates to callers of the extent api.
