From 4d8d9293dce503eb0e083e17a02a328d397e7f00 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Wed, 25 Aug 2010 17:45:44 +0900 Subject: nilfs2: set pointer to root object in inodes This puts a pointer to nilfs_root object in the private part of on-memory inode, and makes nilfs_iget function pick up the inode with the same root object. Non-root inodes inherit its nilfs_root object from parent inode. That of the root inode is allocated through nilfs_attach_checkpoint() function.
