We no longer lookup ".gfs2_admin" in the root directory in order to find it, but instead use the inode number given in the superblock. Both the root directory and the admin directory are now looked up using the same routine, so the redundant code is removed. Also, there is no longer a reference to the root inode in the GFS2 super block. When required this can be retreived via sb->s_root->d_inode instead. Assuming that we introduce a metadata filesystem type for GFS, then this is a first step towards that goal. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
